>Change generally isn't sparked by routine atrocities rumbling along in the background though, but by people coalescing around specific atrocities that gain high profile
Exactly.
Taylor and Shaver are people worth rioting over. Instead we've got protests because some much less sympathetic people were killed in less inflammatory (though obviously still pretty terrible) circumstances. Not exactly what civil liberties advocates were hoping for but there's no reason not to roll with it because maybe the cops will finally be reigned in a little (hopefully a lot but the government always drags its feet about curtailing its enforcers).
Assange might be an asshole weirdo but if he's what gets us reform then why not take it?
