I won’t be surprised if the flag is ordered at half mast. He’s being celebrated as a great American. He may have been a great boxer but he most definitely was NOT a great American.
I wouldn't have been surprised at an earlier announcement. There was this news:
Muhammad Ali's Hometown of Louisville Pays Tribute to the Boxing Legend (Flags at half mast)
"At a ceremony at the city's Metro Hall, Mayor Greg Fischer said flags on government buildings would remain at half-staff until Ali has been laid to rest."
