Police in Peoria, IL invaded a citizen's home and dragged said citizen off to jail for posting to a Twitter account parodying the Mayor of said town.
That's why the cops need those red light cameras and speed traps: ticketing people individually takes lots of time and personal effort. So does showing up at the scene of an auto accident, which they no longer do either.
I used to believe that the police used the time they saved to sleep in their patrol cars or play games on their computers. Now I know they were involved in worthwhile activities like harassing their employers, the citizens who pay them.
