I still don't understand why the police in the USA keeps chasing suspects in cars Over here they stop a chase when it is clear the driver is not going to stop. They use their radios to coordinate a natural road block ahead like a traffic jam at which point they catch the suspect(s) without putting other people's life at risk.
Notice that, in this particular case, the crash happened about 10 miles (roughly 16 km) away from where the chase stopped. So they DID stop pursuing him (though not intentionally -- they stopped because the police car crashed), and he caused that crash anyway. It was in the grid of Los Angeles city streets, so there were many routes he could have taken; not just one route with one natural road block.
If the police have a known policy of calling off a chase as soon as the pursued vehicle starts going fast, then that provides incentive for the bad guys to flee and put lives in danger.
Like chasing a car is the only way to arrest suspects
Like I typed before: there are other, much smarter, alternatives than just chasing a suspect in a car.
If you start chasing someone he/she is going to do stupid things because of the Adrenaline rush. That is what law enforcement should prevent. Let criminals
think they got away until the time and place are there to make an arrest. Over here they use centrally controlled traffic lights, cameras along the roads, helicopters and unmarked cars to locate and block in suspects. High speed chases are very uncommon because of the risks associated with them. The key thing is that you don't have to try and catch a criminal within 5 minutes.
