Is there any complete video, maybe time-lapse that shows the entire cycle of one of the weekend's demonstration-protest-riots? I'd love to see a shot of an empty area just before it becomes the site of something and really see who did what that got it to a stage of bad stuff.
My sense is that if, in anticipation of possible looting/violence/crime, extra cops were at their stations or on call for that work but not preemptively out in riot gear at the start of demonstrations, that'd be win-win.
