"To the dealers my message to you, were coming for you. As a matter of fact, our undercover agents have already bought heroin from many of you. We are simply awaiting for the arrest warrants to be finalized. So to the dealers I say, enjoy looking over your shoulder and constantly wondering if today is the day. We're coming for you. Enjoy trying to sleep tonight, wondering if tonight is the night our SWAT teams blow your front door off the hinges," says Grinnell in the video.
