Jeff's suggestion is a good one, but let's take this one step further. Have you given consideration to a campus safety and awareness course for students? I mean a formal course worth X number of credit hours.
Said course should include techniques for spotting subtle but unusual or suspicious behavior, body language, spotting an armed individual, overall situational awareness, use of cover, escape tactics, etc.
This would fall in line with "Give a man a fish and he eats for a day. Teach a man to fish...."
