Acute observation

I read an online comic called Bunny, which is usually pretty esoteric, but in the cartoon from yesterday they make the kind of pointed observations that I love seeing interjected into the generally ludacris public debate on terrorism:

“Bomb” attacks: Deaths:0, Cost: the same amount of council tax as usual.

Current flash flooding in the UK: Deaths: 6, Cost: Estimated to exceed 1 billion pounds.

Which one is seen as the biggest threat to the UK? The one that was foiled by Civilian emergency services, traffic wardens, concrete bollards, and members of the public.
