Police Character Facts

Police are one of Earth's two protection factions, the other one being the army. 
The police on Earth in the Dragon Ball franchise are all very similar to their real life counterparts. Their main purpose seems to be protecting single city's and towns that do not require the work of the two military groups. Their weaponry and such is also more limited, such as only the use of smaller guns and occasionally Rocket Launchers etc. As far as their transportation goes, they use scooters, motorcycles and different kinds of police cars and hovercars.
