My high school's JROTC program had me receiving firearms training and marksmanship in my HS sophmore year
The debate on allowing CCW on campus is not about allowing 18 year old freshmen to carry. In just about every state, you have to be 21 to get a license, which leaves out most undergrads
If you allow CCW on campus, it will be limited to professors, grad students, and administrative staff. The talk about allowing undergrad students to carry is just to poison the debate
But that sort of wonderful story is strictly limited to certain very narrow regions. Right here where I am in Miami Florida the University of Miami used to have an indoor rifle range but it's been gone for several decades. With the current administration of Donna "Boom Boom" Shalayah (sp?) the former Clinton cabinet member, things have only gotten worse. If she discovers any athlete has possession of a gun under lawful conditions under state law she will have them expelled nonetheless.
Used to be that the major universities in this state (UF, FSU, USF, etc) had full ride scholarships available for students participating with the RIFLE TEAM! No more. Increasingly, this type of thing has become a rural issue...even in populous states like Pennsylvania. I doubt serously you'll see that in Philly, right?
