I feel like the alcohol analogy is apt. We accept the bad parts that go along with it, perhaps because of its wide acceptance. I have never heard a politician trying to limit alcohol supply, hard liquor, or how much you can carry at one time. Why? Because drinking and driving is already illegal, and perhaps a number of those who would drive drunk, likely would find a way to skirt whatever new laws we make up to keep them sober.
It's like guns, in that if you are "OK" with guns, you might be against further restrictions. If you are OK with alcohol, you might be more likely to be OK with possessing as much alcohol as you like, and see the lawbreakers as people breaking an existing law about driving while intoxicated. If I started pushing my "3 beer max" law, so many people would roll their eyes at me. I bet though, there are very sober people who are so against alcohol that they would support my cause. Does that make my cause right? Yes, perhaps less deaths to innocent people would occur. No, because it infringes upon individuals rights to have alcohol, just to hopefully deter the bad apples.
I just read an interesting analysis:

What happened in Vegas is indeed a senseless tragedy, and prayers go out to all affected. It's horrible, and I don't wish an event like that on anyone.
