There IS a need to nitpick, actually. And this isn't to take away from the sad business today. We wimmin have fought and campaigned very hard against extreme bigotry, and are still campaigning hard against extreme hatred in much of the rest of the world, to be viewed as able to do 'any' job, to receive equal pay and benefits as men, and to take on the same responsibilities as men, for doing so. It was called 'women's suffrage' and it's worth noting that millions of women in the world still don't enjoy anything like the same 'worth' as men in the eyes of their societies.
It's very sad that a police officer lost her life today. It's irrelevant, as Colin I believe is trying to say, that the officer was female, in terms of being shot in the line of duty, and in it being a nasty incident, but not something that's entirely unlikely to happen occasionally. We want to do jobs that men only once were thought solely worthy of doing. Now we do many of them, and we can expect to get killed or injured doing them, whether it's riding racehorses, serving in the armed forces, or being a cop.
It's typical of the media to highlight that the dead officer is female: what next? Her age, her marital status, 'pretty'? Irrelevant, but still implying that such women are some sort of employed oddity. And, perversely, that her death is somehow more tragic than that of another dead bloke.
