Great tip concerning keeping your mouth shut, even when you are within your rights. I've been told not to talk until you see your lawyer and not before 48 hours if possible. I've heard of false memories when experiencing traumatic stress. I am hounded by "Tim Schmidt at USCCA" on my email but I have learned a few things from his persistency.
A better tip is not shooting to keep a criminal from running away like you said.
Although if they are in my house with a gun they are still a threat even running away. They are capable of turning and shooting quite easily. That is one situation that worries me because you are damned if you do and a chance (no matter how small)of getting shot or killed. Like to hear your opinion on that. If you shoot the bad guy in your house and the entry wounds are in their back, doesn't look good oldgraygeek.
