I have a hypothetical question for you folks. While watching those cop shows I've seen where big groups of nervous thugs break into suspects' homes, brandishing guns, yelling, and otherwise causing a scene. Good TV, I'm sure, but I was wondering about the moral questions confronted by the occupants, expecially if they happened to have some kind of self-defence weapon handy. Now the occupants only know that some people are threating him, even though they might claim they are police, should they believe them? After all, actions speak larger than words. They just broke down someones' door, as proof of their violence. The occupants don't have actual proof that they are police, now do they?, just the intruders' claim, and you know how people lie. Should the police, in this circumstance, make prior arrangements as to prove that they are police, and avoid this kind of split second decision an occupant in this position would have to make. Self-defence is a proven legal strategy, but would it apply here?
