Consider this from Joe Coffey, a retired NYPD Detective:
During a late 1960s investigation into the mob’s influence on boxing, Coffey got to know Frazier’s trainer, Yank Durham. Thus, when Frazier and his family became the target of death threats and victims of vandalism before his ’71 Garden bout with Muhammad Ali — police suspected Black Muslims — Durham, from Philadelphia, requested that Coffey head the bodyguard detail assigned to Frazier and Durham while in New York.
“We executed this security operation for the duration of the stay in New York, including pre- and post-fight surveillance, as well as The Garden itself. His conditioning routine had to be conducted in or near his [Pierre] hotel room.
“He and I spent a lot of time together, watching Ali berate him on TV with remarks about his manhood, his Christian religion, his looks, and the worst of all, that he’s ‘the White Man’s Champion.’
“Joe turned to me and said, ‘I will be everybody’s champion. I am an American champion.’”
