What scared me about this person cleaning a gun in front of children was the fact that I didn't know him well. I don't know what his training or experience was around guns. If he was a careful man or a newbe and I didn't want my daughter around that. Thousands of people have shot themselves by accident cleaning a gun.
Having a gun in the house means you always have to be aware of other children bieng around. As I said my dad was a cop and the guns were always around, however when children came they were locked up tight. Your child might know not to touch them but what about their friends that come over? It's easy to forget to lock a gun up when you are cooking dinner, the phone is ringing and your daughter walks in with two friends wanting to do homework or your son is upstaires with new friends playing video games that have guns in them. Children are curious and guns are made out to be cool by society.
Children take drugs and know not to.
Children drive without sealtbelts and know not to
Children have sex and know not to
And chidren pick up guns and shot their sister and know not to
I just don't think guns and children are a good mixture.
