No Jack, like most rational adults here, my comprehension is more than adequate. Your twisted logic is one of the many reasons that the citizenry of all the other first world nations end up shaking their heads and asking WTF, on a daily basis, as we shoot and kill thousands of our fellow men, every year. Often, for very little cause.
This is a tenant issue, FFS! You recommend hiding behind a locked door with a loaded shotgun, how bizarre is that? You really think that the silly little door chain, with a pair of 1" wood screws in the door trim, is going to keep an enraged guy from kicking the door in? You are sure you would have what it takes to guarantee they you ended up the only one breathing a minute later? Yea, I know all the macho, cowboy bullshit about how great all the tough gun owners think they are, but reality is a bitch, and so is killing somebody, since you didn't have what it takes to walk out the back door. Or ending up as a stain on the carpet, since your tough guy ass got stomped by a tweeker, before he took your gun, and blew a gallon paint can sized hole in your chest.
The case I referenced is of another tough guy, who though his shotgun would save the day. He killed the assailant in self defense, and still got five years. The reason that he is now a convicted felon? Because he had to be a dumb-assed macho cowboy, and go save the day. The event had multiple witnesses who all were in agreement on one fact, if he had not killed the other man, he would of been the victim, since the guy was out of his mind and wrestling for control of the gun. All of this shit could of been avoided if we didn't live in a society where there are far too many douche bags who think they are Billy Badass because they own a gun.
Solving your issues with a loaded shotgun? How sad is that???????
