I'm not an instructor, but these are ones I've heard earnestly expressed.

You have to get backed into the furthest corner of the house before you are allowed to use deadly force against an intruder, so you need to measure the distance from your front door to the corners to make sure you know which one is the furthest so you can be waiting there to shoot.

If you shoot someone outside, you will be charged with murder. Inside it is self-defense. If you shoot someone on the porch, drag him inside the threshold to cover yourself legally.

If you get a CHL, they'll argue that you are a good shot because you could pass the shooting test that's given to law enforcement, so it is better to carry illegally and keep it concealed and to rely on the legal justification for shooting in self-defense than to get a CHL.

I've read a variation of the above on the forums here with people hearing that they should intentionally "throw" some of their shots when qualifying so they won't look too good in case of an eventual court case.

Edited for spelling. Edited a second time because the spelling was correct the first time.
