Whatever the lock is - it ain't coming off. We (as in us here in the US) are going to have to live with this near (or more) daily reminder that we value our ability to own and carry guns more than our safety, our sanity, or our children's lives. And not just our children children - but every kid gunned down in a classroom or in a parking lot living their carefree lives. If Sandy Hook didn't change everything - then nothing will. Like what could be worse than that living hell those parents live through now.  And if it were your kid who got their face blown off like the kids in Texas. What could you do. What could you change to make a difference so another parent wouldn't have to have the same thing happen to their kid. Nothing. You can do nothing.
