I am glad to see all the experts here weighing in.
I guess the years I had shooting an M16 mean nothing.
A liberal airhead loser was an expert with iron sights at 130 yards.
As a former Marine grunt I have to plead a little knowledge of weapons, particularly the M16. Rifle range shooting for Marines at the time started at the 200 yard line with offhand, then 300 yards kneeling and sitting, ending with prone at the 500. This was all iron sights.
It is eminently possible for a relatively inexperienced shooter to do what the scumbag in PA did. Remember, he was aiming at a human size target, not necessarily just forTrumps’ head. And he missed his target with all other shots.
