No I don’t know.
My view is that the police aligning publicly with any political cause is wrong.
And I believe Pride is political: it was meant to be, that was the point, and it’s still highly contested, as we can see with the sex-based vs identity-based rights clash, with arguments about where Q and T belong, with progress vs pride colours.
That should be a big warning sign for the police to stay clear.
How many police cars would you consider acceptable painted in colours of Labour, Tory, Israel, Palestine, Buddhist, animal rights, farmers welfare, etc etc etc. Would you support a police car in suffragette colours to police a women’s rights rally? Or a trans rights one?
