Agreed.Probably one of the dumbest ideas ever conceived,how anyone would support this idiocy and how it hasn't been dealt with is beyond me.
What I think though is that given the current climate about police brutality, the police have chosen the de-confliction route and have decided to wait it out.
Give it a week or so, wait for the rich kids to get bored and go home and once it reaches smaller levels they can manage it with less "force".
Currently if they go in and the perception that they use excessive force (even if it is perfectly justified) will make these kids to be seen as martyrs and makes their intent to actually seem legitimate.
Wait it out, the kids will get bored and go home.
