Don't get the gub'mint to do your dirty work

I just spotted this story linked by Drudge about some gamblers who cheated to win at several casinos in London.

A CHEF who turned high-tech poker cheat with an array of James Bond-style spy equipment to pocket an estimated £250,000 was jailed for nine months today.

Yau Yiv Lam, 45, and two other partners in crime, repeatedly preyed on casinos throughout London using miniature “up-the-sleeve” cameras and virtually invisible earpieces to reverse the odds and chalk up a string of spectacular wins.

Regardless of whether you think there is any such notion as "cheating" in a casino or where exactly that line should be drawn (I've never understood why using your brain to count cards, for instance, is considered cheating), why is it the job of the government to investigate, to prosecute, and to support the incarceration of those who arguably defraud casinos? Specifically, why isn't it the job of the casino itself to investigate and then pursue action against the cheater at its own expense?

I simply fail to see why the government---and, by extension, the taxpayers who are being systematically robbed in the name of this mercantilism---should do the dirty work of a business that simply doesn't want to foot the full cost of its business. This logic certainly doesn't apply only to casinos, but this is a particularly obvious example of an industry that can and should accept all the consequences of its business model.
