Great line of the day

Digby describes a recent incident in Oakland, CA where a transit policeman shot and killed an unarmed man -- the man was under arrest with a bunch of his rowdy friends at a subway station, all were sitting on the floor, some of others had been handcuffed. The man is sitting with his hands in the air, lipping off at the transit police, when one of the transit cops just pulls out his gun and shoots him.

Officials have not said whether the officer intended to shoot Grant. One source familiar with the investigation said BART is looking into a number of issues, including whether the officer had meant to fire his Taser stun gun rather than his gun. Alameda County prosecutors are conducting their own investigation, as is standard in officer-involved shootings.

I wouldn't be surprised if he did. The police use their stun guns on people who are already on the ground and offering no threat all the time. It's no wonder that one of them would get confused and just start shooting people in the same position. They have no sense of what constitutes a real threat anymore.
See, the problem isn't the form of gun they use, a stun gun or one with bullets. It's that they use any gun on people who are already down.

Emphasis mine.
