Active duty LE only runs right around 800k if not a little less.
The last county I worked in, if we called everyone who lived there, PD, SO, Fish and Game, State Troopers, would have been 14 total, with an additional 3 reserves who lived in other counties.
Other places have hundreds or thousands of officers on duty per shift.
Putting those numbers in perspective, you get a different view of the situation.
