Having been trained, having been in actual combat, and having been involved in a defensive shooting where others caught live rounds and I didn't, I have heavy praise for this article and for the previous post. I would like to add that "preparedness" and all that it involves, will keep a person alive and safe. Preparedness also includes rehearsing "what would I do" in a given situation, and may be the biggest mental device that saves you. Having to defend yourself when the situation offers no choice is not a crime. Prior elaborating on most of the other elements stops me from going further on that. When law enforcement comes into play, you need to keep all of those helpful hints in play. At that point, "Should I tell them what happened", is the biggest issue. If you can present your case without incriminating yourself, meaning can I tell the truth without getting locked up, by all means, give the police all that you can, they will probably appreciate it, if you had no viable options remaining, the true story should bare that out. If it doesn't, you need a lawyer. Keep in mind, killing someone doesn't wash off, so righteous preparedness can make those critical fractions of seconds keep you both alive and out of jail. if all goes well for you, you can still expect the constant instant replay of the incident. Emotional turmoil always follows, even if you know you were right. Be wary of those that may seek retribution, if that applies. Stay prepared, stay alert, stay alive, enjoy your life. I give this same advice to myself, every day.
