Anyone else remember this from Terminator 2 ??

There's an enormous difference between firing at a smaller group of people at near contact distance and spraying indiscriminately into a crowd from a distance. I'd expect the latter to produce at lot more non-lethal injuries than the former.

How can you miss? Easily, once the crowd starts to scatter - and he didn't miss enough times to wound a shitton of people.
