Of interest, the Metropolitan Police Commissioner has risen through the ranks, spending time in every role on the way. He STILL regularly puts the body armour on and gets out on the street. He has been known to get his 'hands on' a suspect in the course of those duties. OK, a lot of it is for show, but he still does it. He hasn't forgotten what his actual job is. A manager brought in with no 'street' experience has zero credibility.
