Build Trauma Kit Video
The good news...75% of gunshot wounds are not fatal; bad news...police are not required to offer medical assistance; doctors are seldom by-standers. If you carry guns, it is a good idea to have your own trauma kit and know as much as possible about self-help.
I ordered several items from Amazon for the first aid kit. I injured myself several times at the range with "slide bite" and various skin pinches with semi-auto pistols. A few hot shell casings hit from neighboring shooters. In younger hunting days, my cohorts nearly wounded me. Do not tell me this never happened to you.
The Chicago video taught me that policemen are not required to give aid and they may ask good Samaritans to leave a crime scene. The Medic video shows fast and dirty quick action that may be best while waiting for the ambulance.
Like everything else, there are legal questions to be answered before trying to be an EMT.
