Hiring protesters?

Who's hiring protesters? I'll just borrow this little bit of transcript from matttbastard.

Conservatives "work for the well-being of people that work hard, and have no time to protest and who don’t have the time to protest, or have the money to hire protesters."

Mr. Harper, who are you accusing? In recent memory, the only people who we can clearly identify as being on a payroll to perform as "protesters for hire" were members of the Surete du Quebec.
