Come to think of it, would you consider it a thought crime if the penalty was worse for someone testilying to deprive you of your liberty versus depriving you of, say, the 2007 Jaguar?
Anyway, I'm sure you have seen this:

House of Representatives Judiciary Committee
December 1, 1998
My name is Alan M. Dershowitz and I have been teaching criminal law at Harvard Law School for 35 years. I have also participated in the litigation — especially at the appellate level — of hundreds of federal and state cases, many of them involving perjury and the making of false statements. I have edited a casebook on criminal law and have written 10 books and hundreds of articles dealing with subjects relating to the issues before this committee. It is an honor to have been asked to share my experience and expertise with you all here today.
For nearly a quarter century, I have been teaching, lecturing and writing about the corrosive influences of perjury in our legal system, especially when committed by those whose job it is to enforce the law, and ignored — or even legitimized — by those whose responsibilities it is to check those who enforce the law.
On the basis of my academic and professional experience, I believe that no felony is committed more frequently in this country than the genre of perjury and false statements. Perjury during civil depositions and trials is so endemic that a respected appellate judge once observed that "experienced lawyers say that, in large cities, scarcely a trial occurs in which some witness does not lie." He quoted a wag to the effect that cases often are decided "according to the preponderance of perjury."<1> Filing false tax returns and other documents under pains and penalties of perjury is so rampant that everyone acknowledges that only a tiny fraction of offenders can be prosecuted. Making false statements to a law enforcement official is so commonplace that the Justice Department guidelines provide for prosecution of only some categories of this daily crime. Perjury at criminal trials is so common that whenever a defendant testifies and is found guilty, he has presumptively committed perjury.<2> Police perjury in criminal cases - particularly in the context of searches and other exclusionary rule issues - is so pervasive that the former police chief of San Jose and Kansas City has estimated that "hundreds of thousands of law-enforcement officers commit felony perjury every year testifying about drug arrests" alone.<3>
