So you are saying that a life is of so little importance that a cop can not be bothered to "find out" where the door closes before shooting 9 shots? No one can get a hold of someone on the TTC and ask, the driver was not around? they couldn't radio anyone?
Guy was inside the street car, he never came out so there was no need to shoot so fast. The point you seem to not understand is that there was time for them to make a better determination of what to do, no one was in immediate danger.
This is the point that drives me nuts, you said "Nice to have time for answers after the situation is done" THEY HAD TIME but they chose to be the cowboy with a small dick and let their emotions and ego get the best of them, hence the out of control swearing and screaming.
If you don't get that then there isn't much I can say to you or anyone else.
