Rubber bullets are very much confirmed at this point.The OPD has been staunchly denying that these were used.
Anyway, there was one report of a guy being assaulted by a 2x4 at the camp. When paramedics arrived, occupiers obstructed them. I have no idea why they would do that, but that's the story. And... that's really the only specific instance of crime that I've heard mention of. Everything else has just been really vague picture painting. Apparently a rat infestation had moved into the camp and conditions were getting unsanitary, which got the camp labeled as a "health hazard". Just how bad it was isn't clear, but I sincerely doubt the hazard was as great as that presented by shitloads of tear gas, small explosives, and soft ammunitions being fired directly at crowds of people...
It's also pretty clear that at least some protesters were being unfriendly towards police. Before the morning raid, there was one incident where someone threw some paint at police, which they described as "assault with hazardous chemicals" in their official press justifying the raid. After the raid and before Oakland turned into a war zone that night, many protesters were throwing rocks and bottles.
I'm off to bed now. I'm sure plenty more info will surface tomorrow.
