When it comes to gun control, I think this point by Jason Alexander is certainly valid to the knee-jerk reaction of "If X kills people, why don't we ban that?"
I'm hoping that right after they hit send, they take a deep breath and realize that those arguments are completely specious. I believe tomatoes and cars have purposes other than killing. What purpose does an AR-15 serve to a sportsman that a more standard hunting rifle does not serve? Let's see - does it fire more rounds without reload? Yes. Does it fire farther and more accurately? Yes. Does it accommodate a more lethal payload? Yes. So basically, the purpose of an assault style weapon is to kill more stuff, more fully, faster and from further away. To achieve maximum lethality. Hardly the primary purpose of tomatoes and sports cars.
I don't think there should be a permaban on all weapons. Obviously, there are good reasons the militia clause is in the constitution. I just really fail to see why anybody should be allowed to easily purchase assault rifles of that caliber.
