well if you go back to the floyd riots, after the first evening of buildings being burned down and shops looted, random violence, why would you do up your laces on your shoes and head out to do some more 'peaceful' protesting the next evening, knowing that it is providing cover for thousands of criminals?
basically because they didn't care about that, more or less condoning it, one of the democrat politicians or tv talking heads remarked 'it's just property'
Cause it it is idiots from all sides taking advantage of the situation, simple as that
