Let me tell you a story about a neighbor I used to have, this man was 45 years old and was lighting off fireworks and hit his daughter in the face with a bottle rocket. Another time when he was "playing" with fireworks, he threw a whole block of firecrackers into a bon fire, you can imagine how things progressed from there. Another time, he gave his 9-year-old son a blow torch to make a snow fort. Another time, he was encouraging his son to do flips into the pool, and when I mentioned to him that his son had gum in his mouth, he said, oh that's okay, I can get it out if he chokes. :roll:
So when someone asks if I think "regular" civilians should have the same weapons as the police, such a grenade launcher and other such specialty weaponry, I have to say a big fat NO. And I am a big time supporter of the second amendment, but a LOT of people are most certainly lacking in not only training but common sense in general.
