Unfortunately standard practice for LAPD is to engage in a dangerous police chase along with the helicopter, not to simply follow with a helicopter.

They don't really use them for hit and run. How could they? Think about how fast that crime occurs and how much time will pass between that incident and vectoring a helicopter, which might be tied up on other work.

Less than 20% of hit and run cases are even solved in California (1). I'm sure the rate is even lower in a city like LA.
