Let me get this straight. You come across an accident scene and there is a person dazed and comatose behind the wheel. So you stand there for 10 minutes shouting commands at them before doing anything and the anything you do next is to taser them? Why not break the window and check to see if they need medical assistance (the EMTs were on the scene you know)? If the person had a heart attack, in 10 minutes they would be dead.
I assume you are talking about this accident, because you got sniffy with my digressing -- but then what you say doesn't make sense since there is no statement in the story that she was comatose.
You are demonstrating my conjecture that to make a strong argument against what the policeman did one has to exaggerate or misstate the case.
