It’s really hard for a police officer to chase down a suspect via surveillance cameras when the suspect being filmed is ACTUALLY THE COP. From the UK Telegraph:
The junior officer, who has not been named, was monitoring an area hit by a series of burglaries in an unnamed market town in the country’s south.
As the probationary officer from Sussex Police searched for suspects, the camera operator radioed that he had seen someone “acting suspiciously” in the area.
But he failed to realise that it was actually the plain-clothed officer he was watching on the screen, according to details leaked to an industry magazine.
The operator directed the officer, who was on foot patrol, as he followed the “suspect” on camera last month, telling his colleague on the ground that he was “hot on his heels”.
The officer spent around 20 minutes giving chase before a sergeant came into the CCTV control room, recognised the “suspect” and laughed hysterically at the mistake.
I suppose this is one reason why a GPS tracker is so much more accurate than manually tailing someone, even with surveillance cameras.
