ABSOLUTELY carry without training is frankly irresponsible. If you do not have solid fundamentals and solid practical/tactical training you should not be carrying.
2- regarding pediatric trauma. The study I am aware of that study. This was a terrible study. When they talked about trauma, they talked about people under 20 years old. The vast vast majority of gunshot victims were something like 17 to 19 year olds are on the streets. Not children going to school in the wrong place and the wrong time. More like people in bad areas like Chicago. Not children. More like 17 to 19 year olds where really they are more like adults. I’ve not yet seen a study talking about legitimate children. Say 13 and under.
