I already stated my opinion on the government restricting the number of guns in the home, that is garbage.
As for carrying a weapon or having one for self defense in your home, no one wants to ever have to use a self defense weapon on anyone. You should hope that you never get robbed or never see someone in danger on the street, because that would be great. But these things do happen, and if they do... you are going to want to be prepared. I carry a sidearm and have a self defense weapon in my home, hell, I have an NRA sticker on my truck. If anything to make someone think otherwise from wanting to attack me.
If the government decides to limit guns to 5 in the house and they all have to be behind a vault rivaling Ft. Knox, then the criminals are going to catch on and realize people can't defend themselves and go on a rampage. If kids are in your home, it is your responsibilty to secure your weapon, if you need the government to convince you to secure your weapon... then you shouldn't have one. If you don't support the 2nd Amendment, thats fine, more guns for us... but don't go trying to screw with my right to have a hell of a lot of weapons.
