It's like a cavalcade of African-American staples from the "Law and Order" franchises.
"Senator Davis" has been on THREE of them a total of ELEVEN TIMES - everything from a dirty cop to a scarily religious serial killer.
I checked - every single one of these actors has been in at least one episode of L&O, and most of them in more than one across multiple series. Dick Wolf, you really are doing your part to keep people East Coast actors employed, if only hand-to-mouth.
