Tons of snitches in the drug business bro. They don't snitch a lot in Europe because compared to the USA you barely have to do any time here, but it still happens. In Mexico you get disemboweled and dismembered live on camera before they hang you from a bridge when they find out you're a rat and yet still people rat over there. Street gang members turn stoolie time and time again, there's just so many if them that every time one goes down it isn't even deemed worthy enough to make the news. Look at the big time African American and Puerto Rican crack or heroin kingpins in the 70's and 80's and just count how many of them squeaked; Frank Lucas? Nicky Barnes? Rayful Edmond? Alpo Martinez? They all snitched. And those weren't some petty ass dealers, those were guys that moved serious weight for years and knew the drug trade better than anyone.

Most people are just self-serving twats and especially in this day and age you aren't gonna find many - regardless of the criminal organization they're involved with - who can take a 50 year sentence.
