oh four 

The derogatory term coined and used by Livonia Police for African Americans. The numerical 0-4 is an archaic code law enforcement once used in police reports for the black race.

The former code NIL (N-word In Livonia) used by Livonia Police was retired once a citizen cracked the code by listening to their radio communications from a police scanner. Due to the scandal, they implemented 'oh four' and switched their police radio to a private frequency that cannot be scanned by the public.

"We have to do a raid in Detroit because fucking oh fours robbed a bank in Livonia".

"Livonia is 90+% white yet more than half of tickets and arrests are oh fours".
