Certain parts of the police force are armed. In peacetime and in @ Trained Firearms Officers with Armed Response Units are armed; as Jean Charles de Menezes will attest.
In the TTW phase, I think not only would many more police be seconded to armed response units, but officers on the beat who are proficient with firearms would be issued them. IIRC in the first few chaps. of TLW there is a scene when two police officers in Scotland shut a road and they are armed with 'Glocks'.
For more accurate information than my memory: http://en.wikipedia.org/wiki/Firearms_unit and http://en.wikipedia.org/wiki/Specialist_Firearms_Command
There is an interesting quote in the first article: one police force has only had to use a weapon once in its entire history.
A few Bones seconded to the RAF and kitted out with RAF roundels? Wouldn't that make life interesting for Soviet intelligence!
That would be wonderful. Probably a 'geekgasm'
