AWL-The 3rd of my 4 adopted children has mental problems-she's bipolar and has what they call a "personality disorder"-I think that's just a catchall for anyone who's not normal. She's grown and out of the house, and I keep all of our guns in a locked, very heavy-duty gunsafe and we're careful with the combinations, but I would NEVER pull one of them out while she was at the house. There's no cure for dead and, even though she's never shown any signs of being violent, you'll only get one chance to make that kind of mistake. You have to be careful with guns. I don't unlock ours if someone I don't know well is over, etc. Lanza's mom should have been more careful.
