I recently saw mugshots of a police officer arrested for misusing the surveillance data they have access to for personal reasons. In the mugshot, this officer of the court looked just like a criminal.

"The police service in England and Wales is "not good enough" and its leadership needs an "ethical reset", Lord Blunkett has said.

"Speaking exclusively to the BBC ahead of the publication of a major report he co-authored on police leadership, the former Labour home secretary said its findings point to weaknesses in leadership, morale and culture across the service.

The report, to be published on Monday, will conclude there are "significant causes for concern" and that police leadership requires a "fundamental overhaul".

What’s a criminal look like?

Before or after their arrest?

I was referring to the mugshot as an aspect of prosecutions. You seem to be asking for something else.

You know it when you see it (/s, a little. It’s true at least sometimes).
