That was a rather different problem than directly harassing the unlawfully searched person.

In that case it was incompetence, gross negligence, and so on. Naturally it's hard to prove in court that the court's enforcement arm is at fault.

And at first the guy tried to sue for damages but that was thrown out - because it's so well established - but still that's the point that should be hammered.

Police can be held responsible if the arrest itself was illegal, an attempt to harass instead of execute the law in good faith.
