The B.C. Civil Liberties Association is demanding an explanation from the Vancouver Police Department after a surveillance video showed an officer pushing a disabled woman to the ground.
The video was taken at the beginning of the month on the sidewalk on Hastings Street, near the crowded United We Can recycling centre.
The woman, who has cerebral palsy, appears to brush an officer who is walking with two others.
