weirdbeards or nutty homegrown dems?
Sounds like maybe nutty homegrown Dems. But I put nothing past the ROP.
I heard stories that they had anhydrous ammonia on site in addition to the tons of ammonium nitrate. Both are used as fertilizer however the anhydrous is often used by meth cookers in the synthesis of methamphetamine. The stories reported several suspicious break-ins with apparent theft of anhydrous. It is unlikely the anhydrous itself contributed to the fire because even though it is 3 parts hydrogen to 1 part nitrogen it is very difficult to ignite. However, the person(s) breaking in may have started a fire to destroy evidence of their theft.
