Watching the news from Columbia University and things are grim.
No, arresting protestors was not necessary and does not assure anyone that Constitutional freedoms were observed. Especially when the disabled professor's cane was violently taken away from them.
@LianaBrooks my question there is, why would a disabled professor be at a place where a protest is *most likely* to be stopped by police in a decisive manner? They're a professor; we can safely assume they're smart enough to have planned that out for the intentional political theater it creates.
Much like the shale protests in NB a few years back, where protesters intentionally posed for photos to make the police look as evil as possible, meanwhile trying to kill the police.
