This was circulating recently and is sort of funny:

LAPD flies quite recklessly especially downtown, where they aren't even clearing the buildings. News choppers fly much higher, well over the skyscrapers, and have no problems getting very tight shots on whatever subject there is down there.

If you follow them on ADS-B you see they really aren't used that frequently at all for calls and end up in holding patterns with nothing to do really before flying somewhere else for a new holding pattern, until their shift is up presumably.

Cynical-me assumes those are the ones running stingrays/imsi-catchers.
