The case to know inside and out on how to respond after a CCW incident is Harold Fish of New Mexico as mentioned earlier. The bottom line is that you need to talk to an experienced self defense lawyer first before you make any formal statements to an LEO. Even experienced lawyers involved in these incidents need to get their own lawyer otherwise they have a fool for a client. No matter what you state on your own, it can be construed in manners in which you can't foresee at the time of the statement.
This case is what not to do after a CCW incident by sounding off on an online blog. These are all public forums subject to legal discovery and can and have been used against people. If you need to vent, do it to your lawyer and him alone.
