> Bomb squad onsite
To plant explosives and blame Americans.
> The crowd outside is distracting from the action on the floor
Yeah, that's their purpose. They're not really Trump supports, and their not really in combat with the DC cops. It's a show. Kabuki theater. You are watching a movie.
> Raising a cross
Fake KKK cross burning inbound.
I mean, fer realz, who the fuck on the right actually does that shit? Another libtard fantasy.
> Planning
My postulate is that liberals are getting ready to launch a false-flag, in which they present themselves as Trump supporters and burn a cross.
This intent is not incongruous with incompetence - the libs are too stupid to burn a cross correctly.
Or I'm wrong, and it's just some dumbass putting up a cross.
