The idea of stop snitching is to ensure fellow criminals do not rat each other out when arrested. So if a drug dealer sells drugs, both the buyer and seller are the sole liability of the crime. They will not drag the other criminal in for a softer sentence or for protection from retribution and is fully responsible for his actions.
This code should not and does not affect innocents and should confess to allow the criminal to be arrested quicker. Even if they are of the same race. So being mugged by another guy in your neighbourhood would mean you can confess to who was responsible for it.
