I was going to say, this is really old hat for the street-fightin union thug scumbags who make up the ratz party in Philly.
They’ve been doing this since Sony made the first hand held video camera in Beta.
Yep, now that you mention it both the unions and the security teams used this tactic during labor disputes to great effect.
I think its a pretty damning admission by the leftwingnuts like the midget at dailykos they know they can’t win on ‘the issues’ and are already making plans to get around it.
