What is police code 1041?

Answer 1

Radio Code 10-41 is "beginning a shift".

Evidence code 1041 pertains to police informants and confidentiality. "Privilege of identity of informer".

The informer has the right to remain anonymous - unless she/he wishes to have their identity made public.

Added: Although there are many agencies that continue to use '10-codes' they vary widely from department to department and area to area, and you can never be certain that a 10-code in one department means the same thing in another. Many department are doing away with the common usage of 10-codes and using 'plain speech' to transmit the same information.
