Many years ago, I read a gun press item that covered the results of untrained-unskilled shooters.
The report stated that most untrained shooters aim high & to the right.
You can't expect a strung out robber or thug to be a expert with small arms but I wouldn't take the risk either.
I recall a 1990s era school shooting where a young kid made headshots with 15 of the 17 incident victims! The boy later told police he NEVER fired any real guns prior the event but he played hours of first person shooter/gun related video games.
think about that
