The retired* Met officer talks about wasting resources, valid point in a period of Tory austerity, but then goes on to say “But there will always be enough to fill a diversity unit to run crazy schemes like this. Little wonder the public lose faith in the police.”
So not only is he implying that diversity schemes are crazy, but then conflating the lack of public confidence in the police is somehow tied to this.
In short; he's an idiot.
The policeman in question has two warrant cards - which carry his names, the people working with him only have to look at his name tag and address him. It wouldn't take longer than a week to get used to it and get on with their jobs, I would presume.
