VANCOUVER – The first Stanley Cup rioter to go on trial admitted to a police officer he broke down upon seeing video of himself smashing windows and grinning during the June 2011 mayhem.

Police interview footage played in court Tuesday shows a very tense Spencer Kirkwood recalling the riot night for an investigator.

He repeatedly told RCMP Const. Cathy MacDonald he had no memory of rampaging through downtown Vancouver following a night of heavy drinking, but identified himself in a video in which he smashed windows at the Telus building.

“When I first saw the video, I thought I was going to jail,” he told the investigator in July 2011. “To be honest, I just started to cry a little bit.”

The Vancouver man, who is originally from Chilliwack, B.C., said he contacted authorities after seeing footage online.

Kirkwood declined to contact a lawyer when MacDonald arrested him after the accused said he “poked” some windows at a downtown building using a city barricade.

He also said during the interview he only remembered drinking at a downtown apartment before waking up the next morning to find more than 20 missed calls on his cellphone from worried friends and family.

“I’m very scared right now,” a man who identified himself as Kirkwood said in a call to a 911 operator that was played in court.

Dozens of people have been sentenced for rioting after pleading guilty, but Kirkwood is the first to go to trial after entering a not-guilty plea.

The trial resumes Friday.
