First thing that comes to mind here...and I apologize if this sounds like a rant and I mean no offense.
If I understand the video's and interviews correctly, he was asked to show a student ID card or leave the computer lab. I'm not sure how that campus works, but any universities I've ever been to, you're required to have a userID and password to even get on the computer period, so if he was using the computer that means he is a student or was a student who is now alumni that still has access (which is normal). He was later confirmed to be a student after the incident.
I've been at 4 different colleges/universities and have never seen or heard of such a thing. I have had my card asked for before upon entry to a computer lab and I see nothing wrong with that, but they ask everyone who comes in. But never any sort of "spot check."
Yagman also said Tabatabainejad intentionally went limp when the officers grabbed his arm because he did not want to participate in racial profiling.
The UCPD has described this as an act of resistance, and has said at this point the officers could not have known whether the student was a threat.
I can understand going limp as an act of resistance, however, once a person is limp you can drag them wherever you want. How is he a threat when he is limp and on the ground? How is he still a threat when he is handcuffed and tasered repeatedly? I counted at least 5 times.
Which brings me to the point of the fact that the officers thought someone could "stand up" (500 times or so) after being tasered repeatedly, and then that oh, let's taser him again and see if that makes him stand up is absurd. According to the articles the officer has been on the force for 20 years or so, he should know better. Tasers have also been known to kill on more than one occassion if I recall when used repeatedly. I can picture that one now...student tasered to death infront of other students begging them to stop after being asked to leave.
Also, after handcuffing him, why not just pull his wallet and check his ID? Oh right, they tasered him already, can't do that now...not with all the other students around.
The school will be out a few million on this one easily. Big mess.
Sorry for the rant!
