Hell, there were 15 precincts and each precinct had an average of ten 2-man cars on patrol at all times, plus a 4-man cruiser [[big four), a couple of booster cars who didn't get runs, and a handful of beat men......24/7.

Of course, you had a department of nearly 5,000 sworn officers. I think it's closer to 2,000 now.
Wow! I envy everyone who lived in Detroit back then - at least for being able to support those numbers.

Today, I can't even get the cops to show up when there's a shooting in my neighborhood.
