I know we have the right to resist an unlawful arrest, and we should certainly be able to do so if that is the situation.
I have also seen a situation where a woman stole a pair of shoes from a store in the mall, and the police had to chase her down. She became very combative and screaming that she was resisting this unlawful arrest and they could not prove she had stolen anything.
It was very obvious that she was in the wrong, but was trying to deny it as long as she could. I am not sure what ended up happening, but it sure caused a big scene it the mall that day.
