How do you stop someone pointing a gun at the police officer without brutality?
How do you stop someone attacking a police officer?
How do you stop someone going for their gun?
How do you stop someone going around shooting innocent people?
etc, etc, etc.
Along with reading your other comments here, I viewed these 4 questions as a bad faith attempt at steering the conversation off topic. When people complain about police brutality, we are not talking about the times when police have to legitimately defend themselves or disarm someone. This thread is specifically about the hundreds of clearly documented examples of unprovoked violence by police in the US over the last few weeks, many of them against journalists, elderly people, kneeling protestors and so on. Please engage with that and don't try to change the subject again.
