Sam, the only offense I do is my biting, brilliant sarcasm. Well, that and my face (perfect face for the ErrorNet).
Even so, my house, the Fashionable Bachelor Pad, is not a free-fire zone. I've worked cases of the gas man, the drunk 15 year old neighbor girl, Fed Ex dude, friend of the former occupant, family member who has wrong address come into the house where it's dark. You need to separate the sheep and goats before you do something really dumb like use your weapon.
Turning on your lights may lead to backlighting. As wise man in Tejas say, "and there you are perfectly backlit, full-value numbn***."
Besides who sez that your lights will work and you do not have to go to them. Wise man in Tejas, "we learn tactics not because we want to use them, but because we may have to." I'm all for hunkering down and waiting for Problem #2, but there are no guarantees. That's why I like a light.
