If I get a group of 30 people to tightly pack in a 20 foot circle around something and then just start firing into the pack.... it wouldn't be to hard to hit one or more people with every shot.
Eyewitnesses said they were packed into a corner of the Safeway building, so there was nowhere for them to escape. If the shooter was standing with his back to the open area, the people would be hemmed in and would not run toward the shooter. Obviously, it was like shooting fish in a barrel.
Right; it was like shooting fish in a barrel. “Marksmanship” is what sportsmen (like Sarah Palin) do. “Wild Shooting” is what criminals do, and if his aim had been all that good, he would have had 30 kills.
