Police. Hated by everyone. No one wants to see you, that's for sure. Victims might be glad you've turned up, but obviously only because something bad has happened to them. I gave that job up for many reasons, but the bile spouted towards the profession was part of it.
I now work in health and safety, so I'm not any more popular! 😂😂
As for barristers and solicitors - I've met and worked alongside many in my careers, and disliked very few. They have to emotionally distance themselves from their cases. The law is often a matter of a game of chess or othello. And when you take it back to clever arguments, interpretations if the law and legal history, it's utterly fascinating but often sadly unsympathetic towards the victims and witnesses. Making a clever legal point does not always make the victim feel better, but should go towards true and fair justice. In theory.
And I'll think you'll find that where they have abhorrent and guilty clients, they express their opinions to others in the legal profession or ensure justice is somehow served appropriately.
For example, I once had a defence barrister ask in Crown Court whether my idiot CPS appointed barrister had considered a Dangerousness Order against the offender (at a sentencing hearing). Despite my having earlier begged my barrister to ask for one, he said he did not think this case required it. The Court disagreed, knew the offender needed to have such an order and made one. It wouldn't have happened had the Defence not raised the issue. She knew the offender was a violent man with a huge history and ensured this case was heard properly. He got 12 years imprisonment before parole could be considered. Brilliant result, despite the prat appointed to prosecute him.
