Horrific Newtown, CT school shooting

[GPK]

I don't know all the particulars about selling a gun (it's been years since I bought one), but I work at a place that sells firearms (no handguns) and I do know that there is a sh*tload of paperwork and identification that goes into selling one, along with a waiting period for State Police background check. Those that do sell the guns are trained to listen for certain phrases and words, and if they suspect something, they are given authority to refuse a gun sale.
