Where's the money?Review Date: 2008-04-23
Dr. Bob is Right on the Mark!Review Date: 2001-12-02
Dr. Bob's advice is in a totally different area. He believes in something called "sectornomics" which means if you look at all the industry sectors and determine which ones will do well in the next five years, then invest in several companies in that sector, your portfolio will do well. Don't worry about which particular stocks too much, just pick the right sector. Pharmaceuticals, let's say. Then, for the majority of the book, Dr. Bob goes on about the various trends in the US and worldwide which will whip the stock market sectors one way or another.
Should you bet on a Japanese resurgence in the next ten years? Don't think so. How about betting on the graying of America? Sure, says Dr. Bob, but remember, Europe and Asia are graying too.
Doesn't sectornomics break the rule of investing that "the only thing that makes the stock market go up or down is a surprise?" Doesn't everyone know about the graying of America? Yes, they know, but no, it doesn't break that rule. Sectornomics means "looking at the same thing everyone else looks at, and seeing something different." Your own perspective can give you the added advantage over the market.
Inspired by Dr. Bob, I began my own personal portfolio based on alternative energy, because I have found out that this sector is about to boom in the next 10 years. A little research (using the Internet of course) and now I have a list of about 30 companies who are extremely well positioned to make a lot of money once alternative energy goes big. The key for me was seeing the big players (United Technologies, Idatech, Xcel, BP, etc.) investing heavily into this sector. BP makes millions of dollars yearly from manufacturing solar cells.
Dr. Bob's knowledge of statistics is absolutely amazing. And his writing style is very approachable.
I heard Dr. Bob speak at an investment seminar in Columbus, Ohio. His speech was good but his book -- excellent. Just buy it. It is the best investment you will make this year.

A very different investment bookReview Date: 2007-01-05
Stein and DeMuth explain that most investment fads are not only unsuitable for older investors, but, worse, they just don't work. They make a point that many people who lost their money in the market meltdown a few years ago should have thought about: If an investment is too complicated to understand, then it should be avoided. In the end, there's no magic bullet; diversification and adherence to investment basics will pay off. The body of the book is devoted to explaining how to do that.
The book discusses various types of bonds, dividend-paying stocks, real estate investment trusts, and annuities. The one thing that is mentioned in every chapter is the basic principle that risk and reward are in balance; the only way to get a high reward is to take more risk. Striking the correct balance is, of course, an individual decision, and the most important part of the book is the discussion about how to combine various types of investments in in a way that balances risk and reward. There are numerous sample portfolios and many specific bond and stock funds suggested-- and also numerous cautions that investors need to do their own research before they buy anything. The authors provide a link to their website, which provides current information and links.
A bonus is that unlike many investment books, this one is very readable. The authors don't dumb anything down, but they take pains to explain things without using jargon. Readers familiar with Stein's TV and movie style of delivery will recognize it here, too.
This is a very valuable book that will provide the reader with a lot to think about-- and a good way to do that thinking.

A must read for EVERYONE!!Review Date: 2008-07-03
They're not here to helpReview Date: 2008-05-18
The most eye opening part of this book was when he explains how someone can be inexorably caught in the "social services plantation," as he calls it:
Joe gets arrested for carrying a joint (or DUI, driving without a license, mouthing off to a cop, etcetera ad nauseum). Joe needs to have the financial resources, familial support, and a very understanding boss for the needed time off to make it to his court appearances, probation officer meetings, court ordered Narcotics/Alcoholics Anonymous meetings, and he needs to make it home from all these appointments in time because he's also ordered to complete in-home detention.
One day Joe's car breaks down on the way home. He calls a tow truck. After the tow truck drops the car off at the repair shop, he calls for a taxi to take him home. He gets home an hour later than he's allowed, and fully expects to hear from his probation officer, but he's sure the tow truck bill, repair shop bill, and receipt for the taxi are enough to prove he is telling the truth. Sure enough, he gets a call, and he goes about explaining the situation. A few short minutes later, the police show up and arrest him for violating his probation. The probation officer tells him that the GPS device Joe is required to carry shows him being in the liquor store next to the repair shop, and any drinking is prohibited on probation. Joe insists he was only in the repair shop, but the probation officer doesn't believe him, and that's all that is required to put Joe in jail.
Now Joe, the kid arrested for carrying a joint in his pocket, is a part of the local jail population for the next month. Career destroyed, family starting to have enough of Joe's getting in trouble, and financially buried by the court costs, the cost of the in-home detention, the cost of probation, and the cost of missing work for the required appointments throughout the day, Joe gives up on living a "proper life" and gets mixed up with illegal activities in the jail, and the process continues. All that from an arrest for a non-violent legal infraction.
I know the above is a long anecdote, but it's a perfect illustration of one part of Carson's subtitle: "How Even a Single Arrest Could Ruin Your Life."
The only part that seems a little bit paranoid in this book is when Carson demonstrates how to make an arrest-proof car, complete with filling the glove box with expanding foam and super gluing the trunk shut. That's a bit much, but still understandable.
The best part of the book are the "Creds" he offers: Sheets of paper that have all the pertinent information a cop would ask for, along with a statement that your lawyer has told you not to say anything in those situations. That's worth the price of the book alone. I'm putting my Creds together right now.
Highly recommended for everyone--especially those in the most arrestable demographic: young, poor, minority males.

However, he could have saved even more people from jail if he had been more forthcoming and graphic about what happens there. The jail population would drop by half if people new exactly what takes place (courtesy of their fellow prisoners) behind bars. As a former police officer and current practicing criminal attorney, he is most definitely well aware of the unspeakable horrors awaiting both males and females in jail.
An Esssential "How To "BookReview Date: 2008-01-27
Author Dale C. Carson is a former Florida street cop and FBI agent. He is presently a practicing criminal defense attorney in Jacksonville, Florida. As such, he is in a perfect position to reveal the brutal truth about how police work, their methods, dirty tricks, and motivations. He stresses that cops do not receive promotions or accolades for keeping the peace, or resolving disputes by negotiation, but are evaluated and promoted strictly on the number of citations issued and arrests made, especially felony arrests.
He goes on go to explain how easy it is for *anyone* to get arrested, a subtitle of the book. Most non-criminal "upstanding" citizens" can inadvertently become caught up in the criminal justice "plantation," to use a word coined in the book. Arrest records can have serious consequences, even if the charges are subsequently dismissed, not pressed, or you are acquitted. Such an arrest will doom you (especially young people) to a lifetime of low paid jobs, since many employers will not hire anybody with an arrest record, regardless of the judicial outcome or merit of the arrest. This is particularly dangerous in the age of electronic information, where records can last indefinitely. Before the computer age, written records often got lost with age. Not so now.
So the only practical approach is a defensive/preventive/proactive one. Sadly, most people with not read this book until it is too late, if at all. The "clueless" people, who don't even understand the basics of the system, but are either petty criminals or non-criminals, because in their addition to their lack of ability to keep court dates (they do not own or do not use calendars or alarm clocks), frequently turn minor charges to major ones by failure to appear and other add-on charges. Probably most of them are not even literate enough to understand the simple advice in the book.
This book explains how to keep from being sucked into the system. Once you are, it will be very expensive to get out, if it is possible at all. Numerous parasites in the criminal justice system, including cops, lawyers, prosecutors, jailers, social workers, psychologists, have a big interest in perpetuating the system. The most important battle to be won is for custody of your body - remember, cops are visually oriented predators, whose main motivation is to arrest you and take custody of your body.
Buy this book BEFORE you get sucked into the system, and save a lot of money and heartache. As noted by the author, if you are a real, habitual, or big time criminal, this book will not be of much use to you - you will eventually be residing at the "Graybar Hotel" sooner or later. This book, however, is a must read for the non-criminal, petty criminal, or "victimless" criminal, or just for anybody that is naive about a dangerous, unforgiving system, in which ANYONE can inadvertently be caught up in for a momentary lapse of judgment.

Best of the BunchReview Date: 1999-12-28
Outstanding effortReview Date: 2002-06-08
For almost a decade Rosenberg traveled through Latin America not shying away from really messy situations trying to make sense of a history of violence and very little respect for human rights. Tina experienced many of the situations herself such as being soaked with diluted acid by the police in the streets of Santiago, Chile, during marches against Pinochet or taking a nightmarish truck bed trip through guerrilla infested Peru. The Latin American economic, political and military elites also had their points of view captured by Rosenberg resulting, as far as I can tell, in a very well balanced collection of personal perspectives on the problem - violence in Latin America - intermingled with background historical information.
Rosenberg is very competent in summarizing the recent history and the roots of violence in Latin America. The author brings the historical review to life by interviewing perpetrators and victims. Violence in Latin America as viewed by Rosenberg emanates from a history of inequality. The native populations and the unwillingly imported black slaves and their descendants have been for five centuries exploited and victimized by greedy white Europeans. The resulting instable societies in turn fall prey of guerrilla groups, organized crime, drug lords, or the old fashioned military economic and political elites. The victimized population looses faith in the state and became passive or takes matters on their own hands solving social problems or even threatening or overthrowing governments. To tip the balance back the oligarchies can inevitably count on the CIA for supposedly counter insurgency help.
It's a chilling book with no solution on sight and Rosenberg didn't even include some remarkable facets of violence in Latin America such as domestic violence in a notably sexist society and the petit and not so petit common crime. Colombia is the first market worldwide for bulletproof cars - Brazil is the second.
It's an important book mainly for American readers since it shows the impact of American interference. Sadly it offers no solution - maybe there isn't.

Good explanation of difficult subjectReview Date: 2007-01-04
The book opens with general chapters that explain why the differences between tax liens and tax deeds, the things an investor must consider when planning such an investment, and guidelines that will help make the process more comfortable. For example, even an experienced investor may have little experience with auctions, which is the method most governments use to sell tax liens and deeds - "The Complete Guide" has tips on what to bring and do in those situations.
Also in the early chapters, Burrell uses real world examples to help explain points - showing, for example, the forms used to register for an auction in Los Angeles. Later, Burrell discusses subjects like foreclosing (the painful part for those of us without thick skin) and getting financing for a tax lien or tax deed investment.
However, the key parts of the book are the tables (I think there are about 20); Chapter 12, which has a comprehensive breakdown of the different state laws; and the exceptionally comprehensive, 60-page (you read that right!) glossary.

You can make money in a tricky real estate market.Review Date: 2008-04-14
This book is not for everyone. As a licensed real estate agent for eight years, I have seen people try to get rich quick using various schemes they have heard about on television or read about in books - with little success. This method is no fly-by-night strategy and not everyone who would be able to invest successfully. Investors need - at the very least - good credit, some ready cash and a willingness to work hard and stick to the plan.
Those who are able to take advantage of the foreclosure niche in the current buyer's market can create for themselves a life making income as a real estate investor.
The authors wrote this book for the brand-new investor, including not only basic information on how to choose and invest in foreclosures, but current information on where and how to find and choose foreclosure properties, current real- estate and foreclosure laws from state-to-state and detailed information on what to expect during every step of the process. The are even chapters on how to rent your new property, if you choose to do so.
While this book is primarily for investors, buyers looking for a home of their own will find this book filled with useful information. Foreclosed homes can be found at bargain prices and home buyers can use these same procedures to find the home of their dreams. Too many buyers, frightened by the headlines, are not taking advantage of a once-in-a-lifetime buyer's market to buy their own home.
Investors will also find the real estate dictionary and extensive list of references extremely helpful if they plan (and they should) to continue to learn about investing as the foreclosure market changes.
The authors do not pretend that making money by buying and selling or renting-out foreclosures is easy and they caution that in real estate investing, money can be made, or it can be lost. That attitude is what makes this book superior to most. If your plan is to buy foreclosed homes with no money down, no assets and no risk, then look somewhere else - an good luck to you. But, if you are looking for a levelheaded approach to real estate investing in the current market, this approach is a winner.
A survey investors will find easy to begin with, making it the perfect item of choice for public libraries.Review Date: 2008-04-04

Homeowners would also benefit from reading this book. The book provides an insiders look at how the foreclosure process works and the way that investors can potentially save them before a foreclosure occurs. The best defense against foreclosure is knowing the tricks of the trade.
The book is user friendly and well organized. Not to mention part of the proceeds are donated to a worthy charity.

By Dan Tynan
ISBN 0596007752
As someone who gets asked questions about Internet use and safety all the time, a book I had been itching to read was "Computer Privacy Annoyances", by Dan Tynan. According to the cover, the book covers "How to avoid the most annoying invasions of your personal and online privacy."
The quick and dirty? The book gives very practical, real-world examples of how your data can be used, yet the author manages to avoid sounding like a doomsayer... even some of the more scary scenarios don't come off sounding like sensationalism, just honest (and sometimes even apologetic) examples of what could very realistically happen. (I thank you, Mr. Tynan.)
I'll take bets on anyone that doesn't learn at least ten new things they didn't know about their privacy rights. Mr. Tynan has taken the proverbial "They" and reduced it to the very organizations that "they" really are. Did you know you can request a copy of your FBI files? Do you know who has the power view it? Do you know who is collecting data on you at this very moment and what they are doing with it?
The book's format allows for a surprisingly fast read. Well organized sections such as privacy at home, on the Internet, in public, at work, and even on a federal level allow for quick chapter absorption. In each chapter, the author states the annoyance, and then the fix. This allows for quick skipping over an 'annoyance' that might not annoy you that much.
I did notice that the author made no mention of the everyday information users give out about themselves without even realizing it, such as usernames that contain birthdates and such. But the Internet privacy chapter is only a small portion of the topics covered in this book. In fact, if I had to find one fault with this book, however, I'd say they lost a much larger audience that could have easily benefited from the book by calling it *Computer* Privacy Annoyances.
As a tech professional, if I could get all my clients, users, friends, family and complete strangers to read this book, I strongly believe identify theft could become a thing of the past. And it might even reduce global blood pressure, too. Bonus!
Required reading for today's computerized society...Review Date: 2005-09-05
Contents: Privacy At Risk; Privacy At Home; Privacy On The Net; Privacy At Work; Privacy In Public; Privacy And Uncle Sam; Privacy In The Future; Index
In this Annoyances title, Tynan looks at a wide range of activities and situations that involve a potential unwanted loss of privacy. Using a question and answer format, he effectively shows how seemingly innocent activities (like booking a hotel room or ordering a kosher meal on a flight) can be logged and combined to build a profile of your activities that may not present a very flattering picture of who you are and what you do (and with whom). While there's the obligatory chapters on spam, online registration sites, and the like, there are also excellent chapters that cover privacy at work (what your employers can and can not do) as well as health record concerns. Things may not be as secure and private as you think they are...
Realistically, there's already more information out there to be gleaned than you'd probably expect and be comfortable with. But by reading and digesting the contents of this book, you can start to reduce your exposure going forward. Even just the awareness of privacy concerns will start to cause you to question *why* a merchant might want certain information. They may *want* your zip code or phone number, but that doesn't mean you *have* to give it to them. Even if this book keeps you from making just one mistake that would lead to identity theft, then it's more than paid for itself. A recommended read...

On mental aspects of combatReview Date: 2003-03-04
The book starts with introduction of Survival triangle: You have to survive both physically, mentally, and legally to fully survive an violent encounter. The authors keep that in mind through the book, while the stress is on mental survival. Next the authors discuss the selection process of police recruits, and the nature of violence the police are forced to encounter in their line of duty. Next they give a thorough explanation of fear and it's effects on a person, and they address the issue of training, as well.
The main portion of the second part of the book (about 100 pages) is real-life stories told by cops, and the author's comments of the events. There is not any tactical reviewing, but the incidents are discussed on a psychological point of view. At the end of the second part there is a chapter of psychological injuries, starting from physical effects right after the incident, going to post-traumatic stress disorder and difficulties with relationships with other persons.
The third part of the book covers the treatment of a traumatic event survivor. The authors cover all aspects: What the survivor himself can do, what his superiors, family members, peers and so on can and should do. The authors also stress that there are many different kinds of encounters that can cause post-traumatic stress disorder other than gunfights, and that all participants of such encounter can develop mental problems, not just the ones who pull the trigger. There is also advise to detectives who investigate officer-involved shootings.
All things considered, this book is a very complete package. It is easy to read and the text is not too "scientific" for a layman to understand. This was the first book by Loren Christensen I have read, but it sure won't be the last!
Not just for Police Officers, invaluable to anyone that's willing to defend themselves with forceReview Date: 2008-01-02
I found the book to quick to read and easy to absorb. The authors make simple explanations of others experiences, and help you understand what works. In particular, the mental preparation for use of force provided by this book is excellent and concise.
It's at the center of human nature to stay alive, anyone that's put in a situation to kill or be killed will benefit greatly from this book.
