Efficient killing or serious wounding of the maximum number of enemy in the least amount of time is considered a good thing in a weapon designed for infantry use.
While I personally do not harbor, indulge or condone fantasies of mass mayhem, I staunchly defend the presumptive right of the civilian adult to keep and bear military-level weapons. This is why the current alarmist misuse of “assault weapon” by our media so irritates me. A true assault weapon has a select-fire (four safety positions: safe, semi, burst, full auto) trigger mechanism, and no self-respecting frontline soldier would settle for less. Were the Second Amendment not gutted, I would be able, as a civilian citizen, to buy what Corporal Doe carries into battle.
A gun is exactly as dangerous as the person holding it.
Personally I wouldn’t want to own a gun that could easily be bump-fired, even though I can see some mild satisfaction in subverting the repressive arms legislation we currently endure. Ultimately I consider such a gun much less trustworthy than, say, a proper assault rifle in good condition. /rant
