Police helo operating over London
Watching a BBC doco recently with the police helicopter chasing down the bad guys of london.
What kind of freedom do they have when operating? Have they got special dispensation to do as they please (within safe parameters of course!) or do they have to still request clearences into the zone when on a chase?
I vaguely remember one bit where the fugitive drove around heathrow and the helicopter was able to follow without a problem, not like that scene in "heat" where they lose him when he drives into JFK!
