Sorry, but if I see someone selling drugs in my neighborhood I am all over it "snitching". You can kiss my grits w/ your don't snitch.
And you are so outraged that you'll make a false accusation against an innocent third party.
How the System works: Drug cops search a "confidental informant" and find certain substances. It looks bad but the search can go away if he gives them a bigger fish. He gives them an address, doesn't matter what it is. When it turns out to be a bust, they want words with him. By this time he's managed to gather some good info, which he supplies, apolgising for the inaccurate previous.
Everybody gets what they want, and where's the harm?
