Yeah, but then he went and blew it by buying a jam-o-matic drum with a bad rep. Well, that and such a minor thing as hosing down an occupied theatre, attempting to blow up an apartment building, etc., etc.
I’d also point out how glad I am that he didn’t decide to go get a 7.62 NATO battle rifle or there would have been a lot more dead people in that theatre. At that range, 7.62 could have penetrated several people before losing significant energy.
Here’s a good ‘field’ comparison of the energy differences between the 5.56, 6.8 and 7.62.

The observations about the Nidal Hassan massacre were that the caliber he used caused the high injury rate with the relatively low death rate because the rounds went through his victims (without transfering all their energy to trauma) and into others behind them.
