My honest opinion, there shouldn't be very many gun free zones (they don't seem to work out too good) even if there is "gun highly unlikely zones".
I wouldn't have half as much problem if universities would have really strict gun rules but said that they are allowed.
Requirements could be:
KY CCDW (What a joke)
5 Professor recommendations
10 years drug/alcohol free
Evaluations every week by a psychiatrist
$100,000+ in insurance if you do any damage
A notarized letter that you are an upstanding citizen that will not wrongly hurt anyone with your firearm.
Meeting all of those would be tough but still doable. If a collage has these rules to carry a gun on campus no one will fault them for a lack of security.
