It depends on what they're snitching on. For example; a couple of years ago I had a large sum of money stole off of me at a bar. At the time, nobody confronted me and told me who it was and for that month's rent, I had to get a loan off my parents. A year later I was at this party. This drunk guy approaches me and says "Hey! You're that chick that got her money stole that one night at _______" then told me who it was, who just happened to be a HUGE drug addict. It was bad enough having my money stolen, but it felt worse knowing it went to drugs. My point is, people SAW him take my money but didn't confront me about it because they didn't want to be a "snitch". If they had, I would have got my money back that night rather than a thief taking it and spending it all on drugs.
