I edited my comment due to my rational not being so good until I have had my coffee......
I agree. I will not be using my gun unless I feel I am under great threat of harm.
I will definitely let the intruder know I have one and that I intend to use it.
Hopefully I will have the presence of mind to grab my video recorder and use that at the same time I am dialing 911.
Yes it will cost money....If I shoot.....
Hopefully I will never have to worry about any of this.
One thing I will not do is wave my gun around at any time......
