The man who "unmasked" the police officers posing as protestors at the Montebello summit earlier this week says an independent judicial inquiry into the conduct of the security forces and their political masters is needed.

"It is bad enough that a police force in Canada thinks it has the right to infiltrate peaceful protests in such a way but the real issue is who ordered them to do it?" said Dave Coles, President of the Communications, Energy and Paperworkers Union of Canada.

"The fact is that these three police officers jeopardized the safety of everyone in that protest, not to mention the safety of the three political leaders, by trying to incite violence during the summit.

"Quebec police can deny that all they want but they cannot deny that their officers were masked, were armed with rocks and were aggressive to me, members of my family and to other demonstrators," Mr. Coles said. "We all know that constables and sergeants of the Quebec Police Force do not make these decisions on their own. What the Canadian public needs to know is who ordered them to do it."

Mr. Coles called Public Safety Minister Stockwell Day's disavowal of responsibility for the incident "cowardly" and "irresponsible."

"Was Stockwell Day in charge of security at Montebello? If he was, he should take responsibility for what happened. If he wasn't, frankly, he should resign. For him to try and put the blame on three police constables by referring the matter to a police complaints process is a cowardly act that would be laughable were it not so irresponsible."
