This is probably an unpopular opinion, and I'd want to think this through more, but I've been feeling recently that libel laws in the U.S. ought to be stronger. We have a massive problem with propagandists (especially on the right, but also the left) using blatant lies to manipulate opinion. The net result is a huge amount of anger & distrust.

There is also massive corruption problem in the police force, because citizens don't really have effective ways to "watch the watchers".

Obviously the cops aren't going to bring charges for the vast majority of these kinds of instances, but they did against Frese because he's a felon with a history of harassing the local police. And not a cute and cuddly felon either: he ran over a traffic worker after threatening to run him over. It's fine for the ACLU to take this as a test case but this is not this sort of situation that is a great test case.
