I think you're more likely to be the first responder after a terrorist attack than you are to be the victim of one.
If a guy blows himself up in a crowd right next to you there is not much you can do.
But if you show up after the attack with first aid gear and the knowledge to use it you could save many lives before the medics get there.
Agreed.
People need to understand what that means. You have no problem dealing with sutures on family members, those that have not seen that kind of thing need some level of training to prepare themselves for the blood and challenge of knowing the best action to take to save a life.
