"A grassroots campaign to discourage crime witnesses from talking to police is partially a response to the war on drugs.
T-shirts and hats with the message 'Stop Snitching' have proliferated on the streets of cities like Pittsburgh, Boston, Baltimore, and New York. The trend has frustrated police and prosecutors, who say the intent is to intimidate witnesses.
The no-snitching message also has been delivered via rap songs and by the actions of celebrities; 50 witnesses to the murder of a bodyguard for rapper Busta Rhymes have refused to cooperate with police, including Rhymes himself. The murders of rappers Tupac Shakur, Notorious B.I.G., and Run DMC's Jam Master Jay have all gone unsolved for similar reasons."
