Once the suspicion of a crime is established as spurious, barring obvious evidence of another crime, what grounds do the police have to remain on the property?

The same mentality was present in spades in the Scooter Libby prosecution: “If we can’t get you for this first thing, we’ll get you for any little mis-step you take in our investigation.” And they’ll keep “investigating” until they come up with something to haul him in for.

Bullshit. If the officers of the law and of the court shouldn’t be pursuing someone for that first thing, the target of their aggression should be free to tell them to fuck off.
