What I was primarily referring to was in a close-quarter, target-rich environment. Think theater seating here, as in the Aurora shooting. The ability to sweep could leave a number of people dead or dying in their seats before anyone could react to take cover.
And my contention is that AIMED fire, even roughly aimed, will put individual bullets (or pairs) into more people just as fast, and will do so more efficiently. Ripping off a mag dump with a full auto will kill people, but it will also waste over half the mag with misses and redundant and peripheral hits.
There's very little for them to hit there that's not a person. Single aimed shots may thus be more precise and waste less ammo, but definitely not as quick as what a machine gun would put out.
But what it will put out doesn't equate directly to the effectiveness at killing people.
It
sounds scarier, but it isn't actually more lethal.
I am quite aware of the limitations of machine guns and fully-automatic fire, but in the right environment it can be a horrible, horrible thing, and cause casualties at a rate far exceeding aimed fire.
I do not share your opinion about this.
I, personally, can put aimed fire onto targets at close range with a simple handgun at rates of something around 4-5 shots a second (not counting transitions), and I'm no pistol legend. Hitting the happy switch is going to toss half the rounds into the background and many of them as redundant shots or peripheral hits. It is a horrible thing, but not the most horrible thing.
From my work with automatic weapons the only hope you'd have of being as bloodily effective would be to LIMIT your fire to contolled bursts of 2-3 rounds per target. Which is more or less the same thing as fast aimed pairs from a semi-auto.
