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.
