No worries, you will get yourself killed. Here is the thing, If the police and military can develop tactics to safely enter a house and raid it with the armed residents usually ending up as the only casualties, so can gang members and thugs. In fact, some gang members have actually went through the military specifically to gain tactical knowledge then teach lower level members who would actually use it. We even saw this in Afghanistan and Iraq in which the Taliban and enemies enlisted in the state military/police just to gain the training offered by the US military.<quoted text> I have an answer for everything because there is an answer for everything! My mind is a lot faster than yours when it comes to self defense. Sorry if you have a cognitive lack in that department, nothing I can do for you there. You might want to consult Vdoc to get a prescription for your brain freeze.
As a side note, you might want to take a course in Krav Maga just in case your lil AR jams on you, Hahaha.
You find that people doing a home invasion are not exactly bumbling idiots all the time. if all you have is a shotgun with slugs (which is essentially a riffle anyways), you better have a few speed loaders near by. I'm positive that with a 4 man crew, trained and equipped with MP5s, you would not survive. And while you are shooting your wife and kids through the walls (who are seeking cover), they won't care who they hit if they are intent on causing you harm.
