So why are we just now seeing this complete video, too late to impact Bowman’s prosecution? The obvious explanation is that the Capitol Police were covering for Bowman. Is there another explanation?

Obstructing an official proceeding is what many (I think most) of the January 6 protesters were charged with. Here we have inarguable video evidence that Jamal Bowman deliberately obstructed an official proceeding. If the January 6 demonstrators deserved a year in solitary confinement, so does Bowman.
