Retaliation for reporting somebody dealing drugs?

Yes you can definately do so... Its called Crime stoppers check out your local crime stoppers office, everything is confidential and trust me we will not find out, unless you wish to disclose your information. Although you need to state the details that way you wont get in trouble when they go search the place. You need sufficient evidence to obtain a search warrant. That will be explained to you in detail but yeah go head and place a tip, you can even get money for doing so...
