That auto switch or 2-3 round burst is a pretty big difference and makes these rifles illegal. its kinda true to say a AR-15 and m-16 share a lot of the same ideas, but they are an old design and fall into the its not broken so don't fix it bracket. To be an assault rifle, the rifle must be capable of selective fire, and fire an intermediate power cartridge the AR-15 that you can legally buy fails in those last two.
A lot of states have banned the AR-15 from hunting anything bigger than a small mammal because the cartridge is not powerful enough. Totally agree that a fully auto rifle is useless for shooting, a bump stock is a good way to waste ammo, one round would hit the target and the other 29 would be hitting clouds.
In a classroom a trained teacher with a pistol would hold so many advantages against a shooter with a rifle. I am surprised that these rifles have been used in massed shootings, I would have thought that a semi auto shotgun with 16 shot mag would make more sense- cheaper, less likely to jam, more likely to hit the target and the shells are much easier to buy with less red flags.
Yes the auto switch is indeed what makes full auto guns illegal (i.e. it's written in the law) but so what? I've explained very clearly that even without that switch you are left with the rifle that armies use in 99.9% of situations. It's a distinction only ever made by gun apologists.
As for "trained teachers" having guns, no. Just no. After several days of specific house-clearance training, knowing I was going to be up against non-lethal fire, wearing protective gear for pretty much every part of my body, fully prepared for what was coming, the adrenaline when we entered houses was fearsome. I'm prepared to bet that a week or a month later and unprepared, I'd have been lucky to hit the house if I'd been shooting at it from the inside in a room with no windows.
You do realise that under gunfire people don't react at all like it is depicted in films? Calm and collected they are not.
This whole thing is fuelled by the NRA (now a gun-manufacturer's lobby) who have a good propaganda message: "Make it a little bit harder for nutters to own killing machines = the government are going to put all gun-owners into Auschwitz". Don't buy the propaganda.
