LOL so your saying the police force has unlimited bodies and infinity people but civilians/criminals(which in real life a lot more civilians than cops 'yeah i know') have limited people? God... wtf is that.
I'm saying this works like in GTA single player rather than real life. You get wanted, you get infinite cops after you, while you are one. You die - chase is stopped, because criminal got punished for his crime (with death).
Civilians are not limited, they can respawn as many times they want (just they can't return / "load game" into the previous chase). Criminals don't respawn as suspects, they spawn as civilians too (with no crime).
