Check out the 12 mug shots/ages of shooters at post link ....
All but Sandy Hook shooter are 21 or over ..... SH shooter STOLE his gun from his mother, didn’t buy it himself. The “over 21” is a knee jerk/feel good provision in the law that will not stop shooters, yet once again will restrict lawful people from being able to defend themselves. I saw one comment that said it’s like getting a vasectomy so your neighbor will stop having kids.

Marco was very explicit in regard to the new Florida gun law...You have to be 21 to BUY a gun but not to use a gun.
