Timothy McVeigh would beg to differ...
The word now is that a nitrate plant was next to the firework plant and that it went up. Who knows. All the virus experts on twitter are suddenly bomb and terrorism experts.
I find that very hard to believe. Tons of explosive material left in the middle of a city for years - just like that.Yahoo says it was 2750 metric tons of Ammonium nitrate which is 2748 more tons than used in Oklahoma city. Apparently a cargo ship full of the stuff was abandoned 6 years and the Ammonium nitrate was put in a warehouse and they just forgot about it.
