Snitching.

[NOBLE]

To me, "snitching" implies that you yourself are involved in a similar type of endeavour. If we were both in the drug game, and I ratted you out just so I can have less competition, that's snitching. But if I have nothing to do with the drug game and have never sold drugs, and I saw you selling it as directly against my interest and going to the authorities was the only way I could solve that, I wouldn't think of it as snitching in that scenario.
