My 86 year old mother answers the door after dark with a .357 in her hand and you had best have a good reason to be there at that time of night, but afraid?
Being afraid or unequipped to answer the door that way is unreasonable and incompetent.

Yes, it is. If someone pounded on my door late at night, I'd have a .38, a .357 or a .45 in my hand, depending on my mood. I'd flip on the porch light and peer through the peep hole. I wouldn't start "firing away" as some on this thread have said that the "gun nuts" would do, I would see what the situation was.
