This was the infamous episode where a man chased two burglars who broke into his house, who then crashed. And of course, the police treated him as the criminal.
They haven't - of course! - provided any more information at all. They've simply sought to justify their position, which is 'leave it to the police'.
Which people would be happy to do, if the idle bastards could be trusted to do the job they are paid for...H/T: Melindi Scott via Twitter
