Earlier quoted context omitted.
If you hide something on my car to spy on me then it's not reasonable to expect it back if I find it. Charging somebody with theft for something like this is effectively rewarding the police for being incompetent. One of the worst mistakes in modern government is pretending that the people 'serving' have more rights and privileges then everybody else. They should have less.
> the people 'serving' have more rights and privileges then everybody else I was told the difference between a policeman and a citizen (via citizen's arrest) is that a policeman can arrest someone for a misdemeanor.
I think the real difference is that the cops have qualified immunity, meaning they aren't at fault even if the arrest turned out to be unjustified, and regular citizens do not.
