Concerns about vernacular. "A Shytty place to die"

The scene when JFK's body was leaving the hospital to go back to Washington. Kenny O'Donnell was heard to say:" A Shytty place to die" ( I misspelled that on purpose IMDb.com won't allow me to write profanity.) I was now alive back but I'm pretty sure they did not say that back then. He should have said "A horrible place to die."

Boston and Philly love to slander us, but they don t have as many fans as us
