There comes a time in every parent’s life when they have to leave their child home, alone, without a baby-sitter. Provided you’re an OFWG living in a low-crime ‘hood who’s not a reformed criminal with a mysterious past, chances are every little thing’s gonna be alright (outside of drug use and teenage pregnancy). That said . . . would you (in theory) leave a teenage child access to a firearm for self-defense? What age? What about a baby-sitter? What gun?
