Precision shooting is an great skill. However, "Safety" does not equal "slow shooting with a bolt action only." That is a falsehood.
Dumping a magazine to gain fire superiority doesn't mean you get it, either. That is another falsehood spread among those who cherry pick the dynamic aspects of combat shooting but don't understand the strategy.
The issue is understanding the military's change in tactics to have increased volume of fire. And it is, in part, due to the fact that more bullets in the air does mean more hits - in fact, that bullets never aimed at the soldier get hits a lot more often than many want to admit.
That is the specific reason we went to smaller caliber battle rifles with double or triple the amount of ammo on the soldier. It does NOT mean that the soldier just blasts away randomly with no intent to aim.
However, with Hollywood and only 1 in 100 who have served now, the memo isn't getting to the shooters. So they have a notion that they can mag dump and still get a hit to stop the "enemy." They see it as a tactic to use against a single target when it's meant for use on a battlefield that has depth, with lines of advancing troops. It's the ones to the rear who are hit by unaimed fire - ones who get up and run into it.
So, in the American idiom of spray and pray at individual targets, it's not what was originally intended. However, from the perspective of a careful single bug hole shooter, even when it's done right, it's still different.
That target that looks like it was hit by a shotgun? Every hit inside an 18 inch circle is a HIT. That is a bullet in a body, reducing that individuals ability to continue fighting. If you get two hits in that 18MOA target, it's two bullets in a live person. Not paper.
That's why military standard is a 2MOA rifle which can hit an 18MOA target out to 500m inside a ten inch circle. At that range, of course you have to aim, and take some effort doing it. But - as combat research explicitly showed from WWI, soldiers in combat rarely take the long shots - because soldiers in combat aren't stupid enough to be visible long enough to BE shot.
The result is that most shots in combat were happening at a range of about 125 meters, when they would be visible in the existing terrain (and using cover for all its worth,) maneuvering toward them, at best in three second jumps.
Go shoot a bolt action against ten randomly appearing targets from 50 to 125m that remain up for three seconds at most, then drop down again. The first thing you learn is that you better lower your expectations getting tight groups, and that ANY hit is better than wasting the opportunity. Second, that a bolt action doesn't work well with you - it forces you to lose the sight picture manipulating the action, and if you get back to back targets you get no shot at the second.
This is why every armed force in the world dropped bolt actions, and then moved to smaller caliber cartridges. And it also resulted in less recoil - which enhances the average humans willingness to pull the trigger.
Once again, take that large caliber bolt gun and shoot 300 rounds in less than an hour. Most won't even try. Yet with an AR or AK it's a half hour or less, and the more serious shooters will put the majority of the hits in the black. That's 280 bullets in human bodies out of 300.
Combat is NOT precision shooting, and "Safety = slow" is a prescription to getting killed. Practice what you like - but by no means are most shooters doing it realistically or even effectively when you blur the situations and complain "they" aren't doing it your way.
Your way may be completely wrong for their purposes.
