According to a report on Instapundit.com, the officers were being fired at AS THEY APPROACHED THE HOUSE, rather than after having busted the door in.
Which kinda makes sense: you gonna tell me a 92-yr old woman squeezed off 3 shots and got three hits on targets less than 10 feet away, and who were somehow unable to overpower her?
Assistant Chief Alan Dreher said the officers had a legal warrant and "knocked and announced" before they forced open the door.
So just what are you after here?
