A couple nights ago my girlfriend and I were laying in bed when we started to hear unusual noises downstairs on the main level. We do live in a double block on a main road so we are used to hearing noises. But my girlfriend and I both thought it was something more than our neighbors walking around opening cabinets and such. So I grabbed my pistol, checked all of my corners while making sure my home was not occupied by an intruder or intruders. I check everywhere in my house my house was clear nothing was stolen and there were no signs of an entry. Thankfully. However I cannot stop thinking about that night and what if two people were in my home what would I have done. I know what I would have done if there was one but what if as I came down my stairs I saw one individual in my living room and I didn't know about the other in my kitchen or my basement which are blind spots from where I was standing. I could could ask the intruder if there are others with him but he could lie and the others could attack me when I have my back turned. How do I contain one intruder without knowing the possibility of others? Any recommendations? Has anybody been in a situation like this before?
