What if the guy killed her? (Score 1)

I just have to wonder how different this conversation would be if the guy was a wanted killer. Here an older guy is in an altercation with a woman, an officer asks who he is 11 times and gets no reply more helpfull than f**k-off. If the cop says ok... I don't want any trouble here... and backs away, gets in his car, and leaves, then the woman gets beaten to death; he would have heck to pay if it turned out the guy was a wanted killer. For that matter, even if the guy was not wanted, and he killed the woman the cop would rightly have been at least fired for not getting a complete story and knowing who to look for. I understand we are heading down the slope to the national number stamped on our foreheads, but honestly; lets get real here...
