With Peter Fonda still walking free, the USSS seems to be doing nothing.
Not trying to Dox, but any Central Ohio peeps here, Rep. Stivers betrayed POTUS last night on twatter. He's up for re-election this year, but 90% of replies are supporting him. Find his twat and express your displeasure and threaten your vote.
He's a coward anyway, and hasn't taken any position up to this point. He's also in the Reserves, so I think he's also actually violating the UCMJ (can't recall)
Fentanyl has a pretty crappy water solubility as well as low oral absorption (it's asorbed much better via oral mucosal membranes).
Water supply would be a shitty vector.
