i mentioned earlier that thier are bullets with loser death rates, no? and you would aim to disarm not kill.
second... with todays tech you can have security cams in you house.. i saw one at wallmart really cheap.. all it does thou is view one door(u would need 1 for each door... that would add up) and let u know if some one comes within sight. easy to bypass from what i saw.. but it would improve your chances of seeing them first. also it is on your turf... u know where the creaky floors and such are at.. u know the ground word.. all this helps.
u can never negate all chances of danger, so u may as well negate it as much as you can.. and guns can help there.
