UCLA Student Tasered by UCLA Police
Nov 14th, 2006, around 11:30 pm, Powell Library CLICC computer lab, UCLA: student shot with a Taser multiple times by UCPD officers, even after he was cuffed and motionless.
According to eye witnesses, it started when student Mostafa Tabatabainejad did not show the Community Service Officer his student ID. He was on his way leaving the lab when a UCPD officer approached and grabbed him by the exit of the lab. He objected to the physical contact by loudly repeating "don't touch me", and this is the point where the video starts.
