This is something I've pondered often and would like to hear thoughts from others.
Let's say that I (a smallish female) am home alone. Being in a semi-rural area, my few neighbors aren't within easy hearing or running distance, and police response times average 15-20 minutes.
Someone knocks on the door. Since I'm home alone, I peek out and see a strange man. I decide not to answer the door in hopes he will go away. Instead, he starts trying to kick the door in.
1. Yell out "I have a gun - stop or I'll shoot!"
2. Say nothing, grab my SD gun & cell phone, and retreat to my safe room to call 911 (with plans to shoot if safe room is breached)
3. Get behind cover and/or concealment and watch the front door while calling 911 - shoot immediately if/when he gets in the house
4. Other (please explain)
I'll go ahead and say I have serious reservations about #1, because BG will immediately know there's a female home alone (who may or may not 'really' have a gun, and if she does, she clearly doesn't want to use it). It ruins the possibility of BG getting in, grabbing some valuables, and taking off without ever knowing I'm hiding inside.
I also have reservations about #2, partly because my safe room isn't very safe, and partly because I don't like the idea of being cornered and trapped in a small room with my back against the wall.
There are probably other things to consider that I haven't thought of yet.
What say you?
