Do you store things in the attic? plastic tubs? How about the basement? cardboard? Do you have wool, paintings, plastic toys, plastic anything, wooden anything? Look around you and the places you keep things. Oh my god curtains they are more or less just flame conduits.
Your couches, your clothes, everything around you is fuel for a massive fire. It can be a bit scary when you really evaluate it. I bet you have never thought seriously about the risk before.
Admittedly at a city level, 3 kilotons of ammonium nitrate in a strategic location should definitely have set off some real thinking but on a personal basis most people are surrounded by fuel and don't think about it at all.
