Sounds good to me.
I would even include long term members of a community, that were agreeable to take the courses to qualify for conceal carry.
This being said, I do think the folks making up the conceal carry team on a given school property, should meet regularly, and be able to vet their members.
For the most part I doubt there would be a problem, but there always seems to be that one person out there who is a social misfit and can’t get along with anyone. There would need to be a mechanism to get that person off the team.
