I mean, there's a reason why the civilian market and manufacturers --
by, of and for trained, professional shooters -- long switched to AR-15 like controls ... to make it easier for any veteran to become familiar with the safety, forward assist and other aspects. That as much as the economies-of-scale too.
What you're saying it just like saying the 9/11 terrorists didn't need to have any flying lessons.
Yes, you do need time on a firearm to learn it.
It's not like a camera, not remotely. In fact, that's
how most accidents happen. If you want to really piss of a lot of law enforcement and NRA members, more than even the media can, have a gun accident based on ignorance.
Furthermore ... the US media says you can mass kill people without much training. No, you can only mass kill people if you go unchallenged ... which is what usually happens in a gun free zone. Otherwise, you'd be dead fast ... possibly by taking your own life before someone else does. I.e., 2/3rds of mass shootings end when the shooter is challenged by someone, other than law enforcement, with a gun.
Lastly, a semi-automatic rifle is
no faster than a semi-automatic pistol. Heck, they sell 30+ and even 40+ round extended magazines for many pistols, especially since most have standardized around the for 9mm and others Glock, like the NATO STANAG in 5.56 and others. You remember the Glock, right? You know why they call it an "Assault Weapon"? It's the hold-over from the same fools in the early '80s who said the Glock was a "plastic gun" that was "undetectable" in metal detectors. Now at the time, anyone who knew anything about physics knew you could not have a plastic gun any more than a plastic car. E.g., the engine is still going to be metal.
But today, with our physics-ignorant society doesn't understand. That's why 3D printers are back in the spotlight. Because the anti-Glock people have taken over the Brady Foundation. The only people even more ignorant than them are Bloomberg's Everytown.
