I'll repeat my original question that started this thread: How and why was this kid able to get his hands on a gun?
That's an easy one to answer. Many parents are incredibly stupid & reckless. As a responsible gun owner myself, I've had many conversations with them. It's like talking to a pile of rocks. They just don't get it. They won't invest in a gun safe or a quick-access lock box for many reasons:
They'll say, "I don't need to lock up my guns because:
"I taught my kids gun safety"
"I told my kids not to touch my guns & they're such perfect kids, they never disobey me."
"I take my 5-year-old kids shooting; they're safe with guns"
"My kids are so smart & special, I can trust them with everything."
"Hey...no one tells me how to raise my kids or what to do with my guns" (I hear that one frequently - especially stupid).
"My daddy never locked up his guns."
"I hid my gun so well, my kids will never find it." (Yeah....my parents hid whatever they didn't want us to touch, but they weren't very smart. While they were at work, we had all day to look for things, and we always found them.)
Another point these parents don't think about. When they don't lock guns up, they're also leaving them accessible to their kids
friends who visit, as well as anyone else who comes to the house. My sister almost learned that the hard way. I argued with her many times about it. She'd always tell me how intelligent & mature her son was, so she didn't need a lock box for her gun. Until her son's 17-year-old friend visited, found the gun & jokingly pointed it at him. Of course, it was loaded. The only reason her son is alive is because the friend didn't pull the trigger. My sister bought a lock box that same day.
How did a 20-year-old kid who was mentally ill (Adam Lanza) get his hands on guns he used to kill 20 children & 5 teachers? His moronic mother bought them for him - along with plenty of ammunition. As a mental patient, her son would be prohibited from gun ownership, so she solved that problem by buying guns for him.
How do we fix stupid? Almost impossible.
