I saw no violence from the man. He was later released and I checked with him at the Pride event on the park that he wanted these pictures uploaded.
My opinion was that the man was escalating the argument with police and might have been able to make his point to more people if he hadn't done so. His tactics - his choice. He can explain his opinion. I think that arrests should be documented by bystanders such as myself and I should not have been stopped from filming.
