The Casey Anthony trial meme stems from the 2011 criminal trial of Casey Anthony, which became one of the most-watched media events in American history. Capturing the public's fascination and subsequent outrage over the 'not guilty' verdict, the meme often utilizes courtroom footage and photographs of Anthony's polarizing expressions during the proceedings. These memes are typically used to express disbelief at unexpected outcomes, systemic failures, or situations where someone seemingly gets away with something against all odds. It remains a staple of dark humor and social commentary regarding the complexities of the American justice system and the nature of media sensationalism.
