A retired public servant who pleaded guilty to firebombing an RBC branch in Ottawa's Glebe neighbourhood was sentenced Tuesday to three and a half years in jail.

The judge residing over the case said Roger Clement, 58, showed no remorse for his crime. Clement pleaded guilty to arson last month.

Although he expressed regret over the inconvenience his actions brought to others and the cost of his incarceration, he never told the court he regretted the firebombing.

Bank surveillance video shown at his sentencing hearing on Monday shows Clement and an accomplice entering the ATM area of the bank on May 18. Clement is carrying a pail of gasoline; an unidentified man is later seen lighting a Molotov cocktail.

Clement's motivations were political in nature. He says the firebombing was in protest of the bank's involvement with Alberta's oil sands, as well as the sponsorship of the 2010 Olympic Winter Games.

Although the video surveillance shows Clement didn't act alone, he was the ringleader in the firebombing. He has never identified his accomplices and -- at this point -- he is the only person who will serve time.

"I think the sentence is a fair one. A considered and fair decision," said Lawrence Greenspon, Clement's lawyer.

Charges against Matthew Morgan-Brown, 32, have been stayed due to a lack of evidence. Another man, Claude Haridge, 50, is charged with careless storage of ammunition stemming from the investigation.
