Actually I was wondering if that was what he was trying to buy when he mentioned the ongoing saga trying to buy "ammo" on EBay in the fraternity meeting, recorded in their minutes. Is that paranoid? Was "ammo" code for AN. He also mentioned some guy have got his address in a concerned way. Just thinking aloud.
"Was "ammo" code for AN."
Ammo ... AMMOnium nitrate. Could be.
You might go do a search on eBay, and see.
