Sounds like a prudent approach to me. The fine looking lady can be admired through the door peephole while waiting for LE to arrive.I'm guessing 3AM. HHMMMM Knock at the door, pistol in one hand phone in the other. Open door? No way in hell!!! Just tell them stay right there, I'm calling you some help i.e. 911, and advise 911 that I'm armed and on the other side of door, and will not open door till I see a uniform officer there. If individual isn't there by the time the police show, I'll give a discription of what I saw. Period!! If I don't know you really, really well, I'm not opening my door at 3AM!!
