Rent a Mobs

Found via Instapundit. An item on professional protesters in the US. While it is anecdotal, I don't doubt it's veracity. Here in Canada we have our own Rent a Mobs that are guaranteed to show up at most lefty protests at Queens Park. Or the groups that also show up with their pre-printed, bordered protest signs, with a nice blank middle to scrawl in the cause du jour. But I do not think we have reached the point, like the US, where they are on the payroll of some liberal interest group. Yet.
