So how much ricin do they usually find?
For them to be calling this ricin, without any chemical confirmatory evidence, means that this was likely a tip of sorts (unless they had some reason to have been watching this guy). I'll wait for chemical confirmatory evidence before getting too concerned.
They are pretty plants. Little big for an apartment, though.

Probably nothing more than a collection of castor oil plants. I wonder who called the feds?
