I'll reply to the comments thread properly another time. Meanwhile I just want to ask a quick question. WAC -- and welcome on board, so to speak -- said:
One little "Americanization" comment. Over here the phrase "armed police" is redundant. They're the police - of course they're armed, all the time.
Fair point, for which I thank you!

What I would like to know, though, is this: wouldn't the police have to give a warning that they might *use* their guns, or is that simply assumed, too?
