Yes--this is no doubt a very political issue...and they are "cool" weapons, in fact I gave a quick thought about owning one at one time...
But I asked myself...is this a "want" or a "need"...and it as most definitely a "want"...
If someone asks themselves that same question when thinking about purchasing an "assault" weapon,and answers otherwise, I would have to question their intent.
I also agree if people want to murder in mass...they will get other items if they cant easily acquire an semi or auto-matic weapon..but the current weapon of choice for these evil and ill people are the assault rifles by a large margin...
So, if you just look at the data and want to solve a problem, any problem, you pay attention to want the data tells you, and then make the necessary corrective action to solve the problem.
