Here is a good question, donuts and cops, why are they associated. Why do cops eat donuts anyway? Well the answer might be a bit more simple than you may expect, at least that’s what my research tells me.
While being a cop can be cool at times, most of the time it involves sitting in a car and searching for bad guys or crimes in some shape or form. Cops also work all hours of the day, and because of this the cops working at night need a place to get good coffee so they can be alert, and not fall a sleep on the job.
So where can cops get coffee 24hrs? Most Duncan Donuts are open 24hrs, and besides coffee they serve (you guessed it) donuts. Who can resist a donut, with their coffee. They are cheap, and packed with sugar.
Of course you can get coffee at convenient stores, and again most convenient stores have donuts or other sugar filled pastries to go with that coffee. Cops also tend to spend time at convenient stores as they tend to be located at intersections, contain people loitering, drunks, and other such high profile people.
Then again it could just be a funny stereotype.
