Three GLARING errors

1) Movie starts in 1966, and the song-track plays "Walk Like a Man," which came out in 1963. Sounds like a small difference, unless you lived through it or are aware of the music history of the era. In late '63 the pop music world morphed into the rock 'n roll era, and a song like this is more evocative of the 50s than 1966 (ever read the lyrics?).
2) Levinson again shows his cultural illiteracy when he has his narrator say "June 1, 1968, the Summer of Love." Duh! Was there nobody on his staff to correct him on such a simple error? Or was he such a tyrant director that nobody dared to?
3) The trial. All of it was pretty absurd, but what tops all was the alibi given by the priest which the defendants didn't bother to mention at all. Again, was there nobody else involved on the creative side this film with perhaps an iota of intelligence?
I could mention other things, like the probability that all four of the guards were homosexual pedophiles, but I'm glad that the truth came out in the end footnotes where all was declared to be fiction. What a waste of 2+ hours. Thanks, HBO! I guess I myself should have known better than to trust the ratings on a 20-yr old film. POS!
