Back to the Pritchard video: Where's the corporal's knee?

As of Wednesday afternoon, the Braidwood Commission Inquiry is peering at the Paul Pritchard amateur video to determine where Cpl. Benjamin "Monty" Robinson's knee was when Robert Dziekanski was on the ground. Was he putting pressure on Dziekanski's neck?

The focus was on 24 seconds in the video, from 5:10 minutes to 5:34 minutes. You can see Dziekanski on his stomach and his head visible. Just below his head, Robinson's sole is visible. Lawyer Don Rosembloom, acting for the Polish republic, argues the angle of the sole of his shoe eans his knee - or some part of his leg - was resting on Dziekanski's neck, thereby applying pressure.

"I know where my knee was and it wasn't on his neck," said Robinson.

Robinson, who was the senior officer that night, is finishing his third day of testimony. He appears to be getting testy. Rosenbloom said when emergency crews arrived, Dziekanki had no pulse.

"If that's what you're telling me," said Robinson.
