Ok...I will try again. I dont understand why someone needs a AK-47 type weapon. However, if you are able to obtain it legally and use it responsibly, I really dont have an issue with that. However, if that weapon EVER (unless you legally sell it) gets in the hands of a criminal and gets used to kill a bunch of people then I (and I think the law should as well) hold YOU personally responsible for that crime.
The main problem I have with these type of weapons is the amount of destruction they can bring in a very short period of time.
