Todd is right. I was about 9 years ago hit by a truck while riding my harley. I was unconsious and taken to the hosptial. I was carrying (legally). When I was awake later on a police offer came in and said he had my handgun and ask ed if I had a carry permit, which my wife then there also showed him and he viewed it and then handed the handgun over to her (unloaded). No sermons, no speeches. I though handled very well..ToddG said:If you're carrying legally and suffer a medical emergency while doing so, you've done nothing wrong. If emergency personnel do call the police, it's still better than (1) not carrying or (2) not getting medical attention. About the only thing I can think of is to make sure you keep it somewhere secure (no one will touch off a round accidentally digging through a bag, etc.) and if you bring yourself to a hospital you might not be legal carrying it inside the hospital depending on your state laws.
Personally, I commend you for taking the responsible step to protect yourself and your family, and I think most LEOs would understand that deeply.
