I did a project on tv/film copaganda a while ago, and one of the most telling things I found was from the 1917 Charlie Chaplin film Easy Street, in which a woman chides Chaplin's police officer character and says "but you promised to reform!" It just goes round and round, decade after decade.

A single federal agent with a long gun just walked through the crowd, slipped on the ice on his way under the police tape.

Dropped his loaded clip.
