Trivia: On a budget of only $3 million, the producers offered actor Donald Sutherland a choice of $35,000 cash for 2 days work or 2% of the film's box office gross. Because nobody in the cast or crew believed that "Animal House" would be a hit, Sutherland opted for the $35,000 cash. As it happened, the $3 million comedy went on to gross over $141 million at the box office. Meaning that Sutherland would've made $2.8 million if he had chosen 2% of the gross.
Answer: There's no indication that the Deltas didn't face legal ramifications from their actions at the parade, nor that Pinto didn't get in trouble (when we last see him, he's literally being chased by the mayor). The film ends at that point and, although the film provides title cards telling us what happened to the characters far in the future, we don't see the immediate aftermath.
