There should be a game where you could play a Cop armed to the teeth and get calls to different Black Neighbourhoods.
With burrs running around all over the place, shouting catchphrases like "He a good boy!" , "He dindu nuffin!" and where you unlock more and more weapons as you progress.
It can go from 12-year olds shitting in a pool and resisting arrest (you start with handcuffs, a baton and a taser) to some real Gangbangers having a shoot-out in the streets.
By the time you get calls regarding gangmembers, you have unlocked Miniguns, Grenade and Missile-Launchers etc.
