A whole 24 officers. Let's see 3 shifts, that's down to 8 actually on duty at any given time. Some will be on vacation, at least one will be at a desk. Say 7 officers on duty. To protect 14,000 students in dozens of buildings across several 10s of acres of land. The newest residence hall alone is 212,000-square-feet. Yeah, 7 cops are going to take *how long* to respond to a nutjob *somewhere* in all that?
At least let the faculty, staff and grad students be armed if they choose to be.
Less than that of course. There's weekends so say 3 shift/day x 7 days/week or 21 shifts per week, with 24 officers x 5 shifts/week/officer or 120 " officer shifts" to cover them. That gets it down to 40/7 or under 6 officers per shift, not counting vacations, the officer in the "command post/office", and the Chief. Say five per shift and you're probably still over estimating the number available in less than an hour.
A lot can happen in an hour.
