Cops should not be shooting people through windows without knowing what’s going on.
No doubt. They should have knocked on the door and announced themselves. Also, if a couple cops go sneaking around a house at O'dark-thirty, shining flashlights around, the last thing they should be surprised to see, is an occupant looking out the window to see what is going on. In fact, they should have expected it. How the hell is a cop so startled, so terrified at the sight of a woman looking out her bedroom window, that he immediately shoots her dead?
