Conrad Hilton Tries Schooling Cops on First Amendment ... Gets an F

Conrad Hilton had another rough night after getting thrown out of a West Hollywood nightclub and then demanding that cops prevent the paparazzi from filming him during his walk of shame.

Hilton, who has a rich history of drunkenness and despicable behavior, was already out on the street with a friend when our photog spotted them. You hear the friend shout to the bouncer, "Who the f*** do you think you are?" The bouncer made it clear who he was, and the duo walked away.
