If it's part of the character and you never reference it, why bother? It's like having Bill be gay, but never be attracted to other women. What's the point of having her be ostensibly gay then? They specifically made Yaz a cop. If she's not going to act like a cop, if being a cop never impacts her character at all, then why make her a cop? It's just bad writing!
My point wasn't the issue with the writing of her character, which is of course not of a high calibre. It was the linking of that poor character writing, to genuine real world issues of the police forces here in the UK, which i found to be wide of the mark. Especially when it's not possible for a succint and informative reply on the real world issues to be had here, due to the rules on political posts (which i wholly understand and agree with).
We are both agreed, it seems, that her character isn't reaping the benefits of good writing in the slightest.
