I wonder if MI5 officers get the same concession. Or is this just
another example of the police bullying their way into getting all
kinds of discounts and freebies?

Most off-duty police officers will intervene if something "kicks off"
in their vicinity.

... which is far less likely to occur in first class, would you not
agree? How very convenient for them.

Still, something probably happens occasionally. What they could do is
have a small number of "first class upgrades" available to police
officers and have a lottery to make them available to those officers who
wish to use the service.
