See if there is any kind of EXIF data in the vid, if this happened before 1:30 for example, none of these people were at Trump's speech.
Actually a proveable fact if this happened before 1:30 p.m. or thereabouts, since Trumps speech ended at 1:11 and it takes 45 min to get to capitol building from there. It looks like it happened early.
Not the only one. We see.
GOOD NEWS EVERYONE
Antifa can never infiltrate a public patriot rally and do crap like this again without being heavily heavily heavily filmed and called out by EVERYONE and most likely tackled to the ground and sat upon until the cops arrive.
That is actually a huuuuuuuge win.
