And yet, he didn’t use a Glock. Something that is less expensive and easier to hide. He didn’t choose that. why?
I don't know. I can't read minds. He was not quite sane though.
My guess, Glocks don’t have enough magazine capacity to suit him.
There are high capacity magazines that fit handguns like the Glock. Also, it's not that hard to reload a fresh mag. But if neither option appeals to him, having an extra loaded handgun or two is another option.
Seriously, nothing he did would have been impossible if so-called "assault weapons ban" was in effect.
Because something about the AR15 was part of the draw for him.
And if he could not get an AR15 he would have stayed home? I doubt it.
He more likely would have used handguns. Columbine happened during the ban btw. Didn't stop it.
Well there you go then. A restriction on AR15s will mean fewer lethally vindictive rage fests with specific targets re likely to occur in the US. Sign me up.
Very doubtful. Even today, fewer people get killed with rifles of any type (so-called "assault weapons" being but a subset of all rifles) than "hands, fists and feet".
This monomaniacal obsession with AR15s by the doctrinaire Left is neither productive nor healthy.
