Ponies that work for the police love their job, but like most things, cops haven't been around here forever.

During the middle ages, there were no police ponies. Instead, there were knights, fighting each other for more land to have for their kingdom.

The Wild West had no cops either. The closest thing to a police officer was a sheriff. In many towns of the Wild West, the sheriffs would always get killed.

Then, towards the end of the 19th century, the police pony was invented. Most police ponies were Irish immigrants, living in the east, or mid-west coast of the United States of Equestria.

Rainbow Dash: Police ponies are pretty important. Without them, things would go pretty chaotic around town.
Fluttershy: I got a ticket for speeding, even though I was trying to get to a friend of mine to help one of their sick animals. At least I wasn't arrested.
Twilight: Man, f**k the police. They going around, arresting black ponies like me, and calling us the n word, it's bulls**t.

Often, police ponies get accused, of abusing African Equestrian ponies, because of their race. This was true during the 60's, and before that, because nopony liked African Equestrians.

Twilight: Man, the African Equestrians weren't causing anypony no harm. Yet, they still got arrested, no matter what they were doing.
Applejack: Racism was common fifty, or sixty years ago, and with police ponies, it got bad. Ain't that right Big Mac?
Big Mac: Eeyup.

Despite everything bad that happened years ago, and the accusations that some ponies make, police ponies today do their work, and are never racist with anypony, no matter what their race is.
