Thanks to the Institute for Justice, I've read of numerous laws which create legal cartels, artificially limiting the people who are allowed to perform certain kinds of work; but this takes the cake.
In Texas, it is illegal to do many kinds of data analysis on a computer without a private investigator's license. According to the printed article in Liberty & Law:
The Texas Private Security Board, the state agency charged with enforcing the law, has issued a series of increasingly aggressive interpretations of the new statute. Those interpretations cleary put computer repair shops on notice that performing commonplace data analysis -- which is crucial to effectively diagnose and repair computer problems -- is a crime. ...
Getting a private investigator's license is no solution because that would require a criminal justice degree or a three-year apprenticeship under a licensed private investigator.
The law is convoluted, and its effect on computer repair shops may have been an unintended consequence of efforts to monopolize elsewhere, but there has to be a reason a state board is aggressively enforcing it. Normally the protected group hopes to get a monopoly on some business area, but what interest would private detectives have in controlling the computer repair business? I could also imagine that it's the result of privacy activism gone berserk, except that the notion that private eyes are especially protective of people's privacy is laughable. The point isn't to protect consumers from prying repair shops; IJ reports that "consumers face the same penalties if they knowingly use an unlicensed repair technician."
My best guess -- and it's purely a guess -- is that some large P.I. firm is angling to buy out computer shops at fire-sale prices and let them continue running while taking in a large chunk of the profits.
Update:Kevin W. Baker's commentary provides some additional insight. It's businesses, not individuals, that are licensed for private investigation in Texas; the business has to have a "person responsible for all activities" who meets the requirements the IJ mentioned. So computer repair shops can make themselves legal by hiring a qualified private-eye "manager" who does nothing except collect a salary. Nice racket.
