A businessman says he was “ashamed and disgusted” after watching himself on a startlingly clear surveillance video firing a gun on board a TTC bus filled with people last year.

Richard Haynes, 29, told court Thursday he was in a “zoned out” state when he pulled out a .45 calibre pistol and fired it at a man who had stabbed him in his mid-section earlier that day during an argument aboard another bus.

“I hope the people hurt by this will forgive me,” Haynes said, his voice choked with his emotion and family members looking on. He pleaded guilty Monday to attempted murder, waiving his right to a preliminary hearing and trial.

Ontario Court Justice Carol Brewer agreed to a joint submission from defence and Crown that Haynes be sentenced to nine years in prison for the Feb. 23, 2009 shooting on Oakwood Avenue near Vaughan Road around 1:15 p.m.

His intended target was struck in the hip and has recovered. A ricochet of the shot penetrated the outer layer of the coat of a female passenger and lodged in the lining.

The incident was captured on four digital security cameras mounted inside the bus. The TTC began installing cameras on all of its surface vehicles at a cost of $17 million after a number of transit shootings, including the 2004 wounding of an 11-year-old girl and a 24-year-old man on the Jane St. bus. A TTC bus driver lost his sight in one eye after he was shot in 2005.
