Recently I wrote about the tragic accidental shooting of an innocent grandmother by a carjacking victim who happened to be a concealed carry permit holder, and who fired at the carjacker. At the time I said this:

Imagine if the same criminal had robbed a police officer who was inside the same house, and managed to carjack his police car. If the officer gave chase and opened fire, would he be facing charges? I doubt it. And if he did, the news media would not be blaming "the bullet."

A few days ago, Detroit police accidentally shot and killed a seven year old girl during a raid. A civil lawsuit has been filed, and while the attorney claims it wasn't accidental, no one is calling for criminal prosecution of the police officer whose bullet killed Aiyana Jones.

In either of these cases, the legal standard ought to be the same, right? So why are they so quick to jail and charge a civilian shoots at a carjacker and hits someone else, but when a police officer mistakenly shoots an innocent person, that's just unfortunate?

I think there is a double standard here. My question is, should there be?
