Wow, you have no idea do you? You don't think criminals like guns as well? Like them enough to know how to take care of a gun? Seriously? If you're betting on that, you're betting on a longshot (pun intended).ALL the gun owners I know (ALL law abiding) practice regularly and maintain their weapon and know how to use it. Most if not all criminals never practice and barley know enough to pull the trigger let alone do any maintenance and get all their knowledge from their equally ignorant friends.
Your entire senario depends on the criminals being unarmed or unable to retaliate. If you want to have a society were guns are commonplace, you have to start expecting that everyone would be just as fully armed as yourself. You will NOT have the advantage here. A mob of that size, armed and prepared to use it will simply shoot first and ask questions later. Much like you claim you would do.If that was me and my home first pound on the door they would have been warned, first foot through the door the first shots get fired and not stopped until the threat is gone. Because in a mob like the one described I would consider it a life or death situation and act accordingly.
Again, your bravado depends on your attackers NOT having the superior force at their disposal. That thinking is terribly flawed. So if you're only brave if you're the strong of the 2 forces, I'd call you a coward.It's not as you say being an internet tough guy, it's just simple statement of fact. I prefer to stand my ground and fight, and not whimper in a corner hoping for the benevolence of the mob. If you do good luck with that.
