There are a couple of points that this topic raises for me,
First, the paragraph about the SF operator whose name may not be mentioned reminds me of the line in the “Mall Ninja” stories about the assassin who was so skillful that “all of Viet Nam still trembles at his name” And for that reason alone, I’m out.
Second, rendering aid at all is a personal choice each of us has to make, it’s your life live it as you see fit. BBP issues aside, I choose not to render aid to a person I just deliberately shot because IMO it isn’t safe. Imagine this, God Forbid you are forced to shoot someone and as you rush forward to render aid he becomes combative again (remember he has no idea why you are approaching him) and you are forced to shoot again and every single witness tells the cops that you shot the guy down than ran up and finished him off at close range. They will bury you under the jail.
Third, training is critical but experience is a must as well. While I was in the army I was assigned to the medical company of a forward support battalion, all the medics were well trained but they spent most of their time in the motor pool. One day while they were in the aid station a soldier had a heart attack right in front of them. Every single one of them (including me) froze because our minds refused to believe what we were seeing. Even when I got a chance to work with the post EMTs I spent a good portion of my first month or so with them doing exactly as I was told to do.
Final thought, unless you are carrying an aid bag around in your car (if you are I gotta wonder why?) you are going to be very limited in the scope of what you can do anyway. God Forbid that you’re a Combat Lifesaver on post (do they even still have those?) and you try to start an I.V. on Academy Blvd because your ass is going to jail for practicing with out a license.
In the real world you’re kinda limited to ABCs; maintain the airway, control any bleeding, keep an eye on circulation, treat for shock, maintain spinal immobilization and wait for EMS.
Then that's what really matters right?
