I thought it was a decent representation of the debauchery going on during that time. Of course, it's an "NBC" piece, so it's going to(at least)slant left...by simply removing characters that are, or have any affiliation with, 'rats...and thus, could potentially put THEM in a bad light.(MSM will have none of that).
PBS has been running documentaries(Frontline series)also on the subject, of course anything PBS(like NBC)I'm sure has a "leftist protection filter" on it.
