Police Academy (1984) 

Police officers were the butt end of many movies during the ’80s, and the entire Police Academy franchise popularized the idea of inept cops. The original movie and its sequels were incredibly popular. 

Even though the actual content and jokes in the movie aren’t offensive, any film or show that depicts police officers being incompetent automatically would be assumed to have a political slant. Considering how much the topic of police comes up in conversation, anything about cops at all probably wouldn’t be considered funny.
