Do I need to worry that my Marijuana dealer would ever find out that I snitched on him?

I'm not really sure how to answer this question. If your dealer is charged, he has the right to know who was informing on him. Typically, cops do not like disclosing their sources, but the constitution requires defendants to be able to confront the witnesses against them. Your communication would have to have led to a search warrant or something substantive I think for you to be revealed though. As far as whether you need to worry, only you know whether your dealer's knowledge is something to worry about. Also, remember, don't ever discuss facts of a case on a public website.

It is possible. On the other hand maybe not. It depends on what the cops do with the information and whether he ever gets charged. If he gets charged and your information is used to help make the case against him it may be given in discovery or his attorney may ask for it and geet the judge to order it. A man has the right to know his accusers and subject them to cross examination in the courtroom.

Concern about disclosure is an issue. That probably will not be done to the dealer by the cops. It might be done by the DA. You should be discussing this with your attorney.
