> I don't necessarily agree that that article proves the IDF is firing on children, there's actually no evidence of that presented in the article.

I think the appropriate term is "circumstantial evidence." A doctor wouldn't be in the position to actually witness the cause of a gunshot wound (hey, maybe all these well-placed gunshot wounds are the result of Palestinians shooting their own kids, I guess would be the alternate explanation...), but let's not pretend that these reports are not evidence of crimes, evidence worthy of investigation.
