I too found that the most distressing part was that the police pretended to have talked to her in October 2020 after her death but that the Directorate of Professional Standards ruled there was no need for further inquiry into what the police did. Then again the English public has only itself to blame. It has always been the Tory playbook to make public services as inefficient as possible before defunding them. You get what you vote for.
This is in London so I assume Met police, which PCC is effectively the Mayor. So if you want to bring party politics into it, the Mayor has been Labour since 2016.
Issues of standards are not really depending on funding but on organisation and leadership.
The issue mentioned above, and many others that have made the news, are down to the Met police management and leadership, which is not supposed to be political. The Mayor is effectively the Police and Crime Commisioner so he has a direct involvement, and again is currently Labour if we want to assign political 'blame'.
My point is that immediately blaming the Tories for everything and anyhting because "that's what you get when you vote Tory" is a knee jerk reaction.
We're discussing standards or professional conduct.
Funding gets you more police officers but their conduct depends on management and leadership, not on extra funding (at least as long as funding allows for decent salaries).
In this case, and again others that have hit the news, funding is quite irrelevant, the issue is organisational.
