Many of the activities popularly attributed to the Black and Tans may have been committed by the Auxiliary Division . For instance , Tomás Mac Curtain , the Mayor of Cork , was assassinated in March 1920 by local RIC men under the command of an Inspector General who had been a ' plague on the local Catholic population ' and the shooting dead of 13 civilians at Croke Park on Bloody Sunday was supposedly carried out by the regular RIC , although a small detachment of Auxiliaries were also present . Most Republicans did not make a distinction , and " Black and Tans " was often used as a catch-all term for all police groups
