> E.g. 1 in 20 kids see someone get shot every year, so you would expect that by age seven that 7 in 20 would have, which is in fact exactly 35%.
This is insane logic. Think about your 20 closest friends. Do you think that 7 of them saw somebody get shot by the time they were 7? I don't know where you grew up but that is definitely not my experience! Continuing the same reasoning, 60% of all 18 year olds should have seen someone be shot. Again, not where I come from.
Supposedly it is at least 22.2% by ages 14-17 though, so perhaps 25% by age 18. So it is the same order of magnitude at least as the naive assumption. My point is just that exposure to violence isn't especially rare across the entire population.
