>Enjoy your dwindling customer base.
Information about defunct sellers on the black market is quite hard to find. Sure you have attempts such as Silk Road that try to keep a good track on things, but that hardly even worked for them then and is hardly working (as far as I know) for the new silk road now.
As I stated earlier, the black market due to it's nature perverts the flow of information.
>The government also killed thousands by deliberately poisoning alcohol.
Wouldn't surprise me.
>Police will oftentimes take anonymous tips. If Bob puts a bunch of filler in his cocaine, just call up a hotline and tell the police he's dealing. Hell, get some of your friends that also got burned by him to do it too, so they have more reason to act.
That's IF anyone actually pays attention to your tip and that's IF one even goes about sending the tip (especially for the situation you described0. I'm not denying that these things happen, but the point in question is that most people won't say anything because again, it doesn't look too nice hopping up to police confessing about a drug dealer who sold drugs to you and your friends. Most people are not keen on reporting someone else along with themselves, and while this can definitely be beneficial for an individual (such was the case with most members of the mafias in New York and New Jersey), but one has to keep in mind that this is rarely the case at all.
