If you suck as a parent, or if your kids have moral or mental problems, then accessible guns are not a good formula for success.
Bottom line is a lock only keeps honest people honest, and guns don't leap up and start blasting away.
PS dont project YOUR insecurity on me and my family. We live in a world where reponsible people are expected to operate dangerous things, and make tough decisions. Deal with it.
If you have kids... Lock your damn guns up!
