Restraint.

I personally don't know how these Occupy Oakland participants are able to NOT retaliate against this police violence by finding and throwing the heaviest thing they can find.

They need to be praised for their restraint last night, but if there is an escalation, we all need to remember who it was that started the violence.
Scott Olsen, the 24-year-old Iraq War veteran injured (and whose rescuers were attacked) by police in the above video is in the hospital in critical condition. He was never shot or injured in two years in Iraq -- he needed to come home for that. Send Scott your best thoughts, and support #OccupyOakland, because they are not giving up.
