You know, I know I'm going to be branded a "Yeehawist" for this, but let's turn a couple of these assumptions back around:
1) Yes, Awerbuck is right: if it's a hit squad of SWAPO terrorists and you rack your shotgun, they won't flee; instead, they'll just fire their AK's through the wall at your now-revealed position. The intruder should hear no sound before you yell "VC in the wire! Blow your claymores!" With all due respect to Mr. Awerbuck, at least in my neck of the woods, nighttime petty burglars outnumber nighttime SWAPO hit squads by about, oh, several zillion to none.
2) You are crazy if you don't call the cops. You are crazy if you give away your position. Hmmm... Riddle me this: how the heck am I going to call the cops without giving away my position? I am not going to be whispering, I am going to be enunciating loudly and clearly; I don't want Suzy Dispatcher to dick things up because she couldn't tell my "C's" from my "V's". This will not "give away my position?"
3) Remember that "Problem #2" thing that El Tejon always rattles on about? I really don't want to shoot anybody, because I really don't like the legal aftermath of a shooting. Especially shooting a teenage burglar from my carefully concealed ambush position. I'd rather, given the odds of it being a burglar versus the odds of it being a terrorist hit squad, let them know that I'm home, armed, and on the phone with Johnny Law before I can see them or they can see me. If they keep coming after receiving that information, then you can pretty well assume that they need shootin'.
