Shoot Viki Weaver through the head while she is holding a baby in her living room...... that is not sniping, that is murder.
A bad deal, but people forget their son Sam was the first to be shot when the family dog sniffed out the agents hiding in the weeds. If I remember correctly the agents shot the dog when it started barking and Sam shot off a round and ran back to the house. Didn't make it, shot in the back and died while his parents watched, not able to help.
