Honestly, I’m glad he only hit 3, and may not have killed any... but how incompetent must one be to have an AK-47, easy targets who have no place to hide (people on a train are as close to “fish in a barrel” as I can imagine), and he has extra magazines for added body count... and he can’t hit more than THREE? Not only is he Evil, he’s utterly useless.
The marines jumped him when he came out of the bathroom after they heard him loading the AK in there.
