Except no one shows up.
The day before the faux convention, one of us sets up a CCTV system and we see how many feds show up to the party.
Bonus lulz: hopefully the different agencies don't know they're being set up and since we know they never coordinate with each other... they are all going to try to shake down each other by engaging in a ton gay sex and drug use.
Chuds show up and get in a gun fight with three different federal law enforcement agencies and the whole thing is disavowed and said to be a false flag and/or justified shootings of violent communist militants.
