The more I hear about these "rogue elements"
…the more I think it’s code for “undercover cop inciting violence”.
If you’re in a camp or protest and you see someone getting violent, encourage those around you to push them towards the police.
Then see what happens next.
I’m betting it’ll be like this:
OWS: “Here’s the guy that threw the brick.”
Cops: “Er… Hi Dave.”
Dave: “Crap.”
Awkwaaaarrrrrd….
