The confrontation should have never happened. Jaywalking shouldn't be a crime, period. Crosswalks create a very false sense of security and people around here (college town) walk into them without even looking. Some people skate or bike through the crosswalks without a second thought. As a driver coming down the street at 30-45 mph, it's a bit hard to swerve or brake safely to avoid these surprise pedestrians. If I were to hit one, though, I would be the one at fault. Jaywalking in general has its own best punishment, which is that you shouldn't just fling yourself into the street out of fear of getting injured or killed.
I'm actually in favor of safe crossings whenever feasible. We have several of these downtown and in the campus areas. There are bridges over the street, or tunnels under them, which provide safe passage for heavy foot traffic in congested areas. I'm also greatly in favor of drivers yielding to pedestrians already crossing when they're trying to turn right, etc.. This should come from common sense on the part of everyone involved. In pedestrian vs. vehicle, the vehicle has a huge advantage. Be aware of it. Don't be dumb.
Having said all of that, once the policeman was in the situation, and once someone went to shove or punch or whatever you want to call it... at him... his reaction was the same one most of us would have if we were physically confronted that way. He responded with a similar category of force. It's not that she shoved him and he shot her. It's not that she shoved him and he tazed her. She shoved him and he shoved back.
I am incredibly curious as to why none of you are similarly angry about the male towards the end of the tape who is NOT an officer grabbing and lifting a woman out of the scene. Is it because you believe he is protecting her? I'm surprised none of you booed him for pulling the second woman (who was still pushing and shoving at the police officer) off. If this second man thought physical force was warranted in order to stop the altercation from escalating, and none of you found fault with it, could it be the problem you have with the uniform the cop is wearing that's clouding your judgment a little?
Oh, and the girl in pink? She was so traumatized that she can be seen in the back of the police car grinning at the camera at 1:37 or so.
