You are misinterpreting the situation: She is asked to take her shoes off, you have obviously not been arrested before. It is asked by police in order to prevent suicide attempts. She is throwing them, that's how the police attacks her.
Again, what the police was doing wrong on many bases in your example.
However, what you are doing is also wrong: We have started this thread to analyse an incident and you are trying to get a general policy out of this. But moreover, you brand anyone who tries to understand the situation as if they were categorically "the police lovers". No, someone might dislike the police in general, but still can evaluate the case submitted in OP within its specific context.
