I grew up in a house full of weapons and just regular old gun cabinets. I remember my father and brothers listing all of their guns for insurance purposes when I was younger about two hundred years ago (it seems). Actually, it was only a little over forty years ago, but who's counting.
Anyway, we had forty-two riffles, nine pistols, and half a dozen shotguns listed on the homeowners insurance form. I was taught to shoot at a young age, and so were all of my siblings. No one in my family has ever been shot by accident, though a few of us have given up some flesh in defense of our country. No one in my family has ever accidentally shot anyone either. We were taught gun safety and respect for firearms since before we could walk and talk, and have never had a mishap due to ignorance or lack of training. The worst that's ever happened to any of us is that both of my brothers have scares on their foreheads from letting a hot loaded .44 creep back on them at the shooting range, I guess they got out at the shallow end of the gene pool.
As for me, I hate the trigger lock laws, and such. I keep my P-38 hanging in a holster next to my bed and the magazine in my night stand drawer for ease of access. My son, the youngest person on the house is eleven and knows not to touch any of my guns without permission and supervision. I also keep my Remmington Model 1100 with two rounds in the mag and the chamber empty in the corner next to the bed. (The shotgun is my primary home defense weapon: I'd rather throw buckshot than 9mm rounds if it comes down to it, but remember that the term scatter gun doesn't really apply, you still need to take aim because the pattern at home defense range, usually fifteen feet or less, is usually small enough to cover with a tea saucer.) My first line of defense is a one-hundred-ten pound Great Dane (I'm a firm believer in organic burglar alarms).
As far as some inquisitive visitors, what the hell is a visitor doing in someone's bedroom? Anyone visiting my home is a trusted friend and isn't going to go nosing about in my bedroom, and darn sure won't mess with any of my firearms without express permission. When I am not home, the guns are locked up where they won't get stolen: any other time they are where I have quick access to them.
Keeping trigger locks on, or storing home defense weapons where it takes you precious time to get to them, is not a good strategy in my not so humble opinion.
Sure, protect your investment and lock them up when you aren't home, but protect your life and keep them handy when you are. Teach your kids not to play with them, including spending time on the range with the youngsters, and don't give guests free run of the house. Get a big dog and learn to listen to the animal and not just yell at it to shut up when it barks in the middle of the night. Then you can get a good night's sleep once in a while.
