Handling large-crowd situations can be really, seriously difficult. A peaceful group can turn to a mob in a second. Sometimes, the precipitating event isn't even an event; a simple rumor will be sufficient.
Agreed. I also have some long-ago experience in crowd control (meaning not on a friendly basis), and I know this is very difficult.
What disturbs me is that now I've seen multiple video versions of 3 different events (Oakland, Davis, and one of the NY sweeps) that very, very much appear like the police in question are deliberately, willfully trying to start a full-blown, violent riot.
Davis, in particular, was, to me, deliberate, obvious provocation. The oakland shooting (ok,with a tear gas cannister, but a 3" skull fracture from a projectile is a shooting, sorry) could have been stupidity or ignorance. I'm undecided about the beating up of the reporter in NY with the words "tonight you aren't press, there is no press tonight". Loose cannon or deliberate intimidation, its bad either way.
Doing incitement, as the police, in a situation involving a hostile crowd is at best stunningly ignorant and irresponsible. It's putting everyone in danger.
At Davis,when you see the guns raised, I still contend that was seconds away from multiple deaths. The police seemed to do little to defuse the situation after they incited it, and it appears that the protestors very pointedly defused the situation for the police.
And that is fortunate.
