My guess is that we’re going to get a law anyway, and my hope is that it will consist of small measures that might have some tiny actual effect, like restrictions on magazine capacity. I’d also like us to encourage people to gang rush shooters, rather than following their instincts to hide; if we drilled it into young people that the correct thing to do is for everyone to instantly run at the guy with the gun, these sorts of mass shootings would be less deadly, because even a guy with a very powerful weapon can be brought down by 8-12 unarmed bodies piling on him at once. Would it work? Would people do it? I have no idea; all I can say is that both these things would be more effective than banning rifles with pistol grips.
This is one of the worst, stupidest, and mist shameful things anyone has said in the wake of this tragedy. Expecting 5, 6, 7 year-olds to rush a shooter? This is a new low in both gun-nuttery and right-wing nut-jobbery.
