I have no problem with people owning guns, IF they have actualy undergone saftey training, and store the gun in a safe manner.
However, I dont get how people think that having a gun in very quick access (eg, beside the bed) is going to help, because if you need it that quickly, then it means that it may quite possibly be too late.
Not to mention that if you live in a very high crime area, getting some sort of passive security system (secure screen doors, window screens and the like, and if you are afraid of not being able to get out in a fire, get some sort of interior operated quick release), because by the time you have been woken up, the invader may have already done some damage (especialy if they have invaded for the purposes of sexualy assaulting someone in the house), by having some sort of secure doors and windows, even if they did get in, the noise would be more likely to have woken you up.
I would also point out that I see no reason to have something beyond a shotgun for home defence, as a rifle would risk doing collateral damage due to going right through the target, and you also need to take into account that the person
might not go down right after being shot, and if they have a weapon themselves, may be able to get a shot off at you (especialy if you only have basic, civilian-level training in firearms).
To continue on for those who have guns for reasons other than self defence, you don't realy have any reason not to have a secure place to store your firearms, that is lockable, with ammo stored elsewhere.
