I agree on wearing it!

But......the message SHOULD be:

DO NOT SHOOT AT ANYTHING YOU CANNOT 100% POSITIVELY IDENTIFY!!!!!

And, even then, be aware of your surroundings and the possible bullet path.

A message I gave my son, and all the other kids that I have taught, is that once you pull that trigger and send that bullet on it's way......there is no 'do-over' or 'my bad'. This is REAL and that bullet will probably be taking something's LIFE. Be sure of your target and aware of the results. Every shot could have an impact on the rest of your life.

There is a huge RESPONSIBILITY that goes along with a gun!
