The term 'unlawfully hang' can be summarized by the crossword solution 'LYNCH'. Lynchings were a form of extrajudicial punishment that was used in the United States, particularly in the South, during the 19th and 20th centuries. It involved a group of people, often white supremacists, taking the law into their own hands and hanging a person, usually an African American, without a trial or due process. The practice was widely condemned and eventually outlawed, but it still has a lasting legacy in the United States.
