Where do you stand on the notion of people defending themselves or others from the police?

Never mind the point that you’re likely to be killed by the police if you try to do anything. I’m asking for thoughts about what the law should allow.

It’s a tricky situation. The police are trained (and dear God, I hope there is some psychological screening process during training). They surely understand the nuances of a situation better than most civilians. It would never do to have untrained civilians interfering with an arrest, even non-violently.

On the other hand, the police do harm people, causing excruciating pain to those who have surrendered. Or injuring them. Or killing them. It would never do to have civilians stand by while armed pain experts cause serious harm to other civilians.

The fate of the nation is on your shoulders once again: what is your solution to the problem of Joe Citizen’s civic duty to assist other civilians being harmed by rogue police officers?
