This may be the best option, but it's not something everyone is willing to do.
With great power comes great responsibility. Guns provide an individual with great power. Too many people take it for granted. I respect Rob Pincus very much, and have learned a lot from his videos, but if it comes between keeping a loaded firearm (locked up even) in my kids room, or keeping it on myself, and all the others in the "big safe" that's a no brainer. I'll keep it on me. Why? Because having a gun for HD is an incredible responsibility. Kids are WAY smarter than we give them credit. If they want in that safe, they'll get in. Then guess who's responsibility it is if something happens? No thank you. It's not a burden to have a gun on me all the time.
