In light of events, demands of the party, take your pick.
Also I think I'm right in saying that the lack of armed officers isn't the problem, it's everyday policing and intelligence gathering thats the issue.
We've got people here posting about the bobby on the beat, sight which was a bloody rarity even during the boom years of Labour. It's not even where the Met wants to have its people. Intelligence gathering is another matter, however, but one that neither of us knows the answer to. We still can't follow absolutely everybody on the watchlist.
There do need to be more armed officers away from our largest cities in my view, so as to bridge the gap in capability/response times. Parity it wont' be, however we can do better than at present.
Counter-extremism is the thorny one, yet possibly the most important as well. I've read suggestions by Muslims on this forum that government would shy away from (well except UKIP perhaps). On the one hand, a government might to deal with a rogue Imam/mosque; on other, such religious leaders represent the first line of defence.
