Its a difficult one. On the one hand, he appears like a nasty piece of work who will likely spend the rest of his days fighting off the loving advances of Big Neville in the shower block. But on the other hand, until he was sentenced he was innocent in the eyes of the law. Unless he went through a disciplinary process he couldn't be sacked, so he was suspended pending the disciplinary - but that also could prejudice the court case so he would likely have been on a paid suspension until a verdict was reached.
No, he's in the job as a police officer because the position of power allows him to act with levels of impunity which would not otherwise be afforded to him.
As usual the Met is saying that it and it's public servants are unaccountable for not gettng rid of this pervert and saying nobody will be brought to book.
