Chopper Chasing?

After the Rolex store daylight robbery, a bunch of commentators said that the helicopter had followed the suspects back to Englewood before six were arrested.

Now we get this story a few days later:

• A black Chevy sedan led Chicago police on a chase throughout Chicago Tuesday evening.

  Chopper 7 was over the chase just after 5:30 p.m. It traveled from the Northwest Side to the West Side. Police cars did not appear to be in pursuit for the entire time.

Um, then that wouldn't (technically) be a chase, would it? 

But if they were followed, either by one of the helicopters or a drone (which we're told might be federal and based out of DuPage airport), then that would be a step up. No bad visuals of chases that go wrong, no cops injured, any crashes are directly attributable to the criminal.

This would actually be an intelligent move, a rare occurrence for certain. We just have a heard time seeing the helicopter up with any meaningful flight time given the maintenance issues they had a few months ago.
