The point of the alcohol suggestion is to show the hypocrisy in their statement.
But that aside, no one "needs" an AR-15 but if you want one and you can afford it then you get to have one as long as you aren't of some list where you shouldn't have a firearm (dangerous felon, dangerously mentally ill, underage, etc.)
LE? Yes
The public? Yes
Hunters? Yes
Ammosexual? Yes.
Please elaborate. What factors did you consider in your answer -- that "no one needs an AR-15" ?
Is it your position that an AR-15 has no unique qualities or capabilities that make it a better choice for specific applications or operators?
Being that the M4/M16 versions of the AR-15 have been used by thousands in the military, plus the number of law enforcement and gov't agencies, does it not follow that someone in need of a rifle would need the model they are more familiar with in terms of use, capabilities and maintenance?
Maybe your definition of "need" is more exclusive. My definition equates "need" with "requirement", which is one or more specifications which a chosen rifle must meet.
I need a rifle I can afford.
I need a rifle for hunting small game (varmints) and which doubles for personal protection.
I need a rifle that doesn't cost me an arm & leg for ammo.
I need a rifle that is reliable.
I need a rifle with very light or manageable recoil.
I need a rifle with about a 600m max range.
I need a rifle that's easy to maneuver in close quarters.
I need a rifle I can adapt for a variety of circumstances and purposes.
Those are needs. i.e. requirements.
We aren't talking about need in the sense that you can't survive without one, like "I need food, water and oxygen". it's more in the vein of "I need a truck I can afford with a bed capable of carrying 4'x8' sheets of plywood and wallboard." When evaluating what products exist you can afford, you'd eventually decide, "I need a Toyota Tundra", or a Ford F-150, etc.
Needs don't change just because there are other suitable options. If I decide I need an AR-15 to fit my requirements, then it's a reasonable and logical conclusion that I need an AR-15. No one is saying we'll die without an AR-15..
