The article mentions Barry Washington, but I suspect that may be a mistake[1], and that they may be referring to Barry Cooper who after years of making lots of dodgy drug arrests and training other LE officers the same; infamously changed sides and now sells DVDs to the public that teach how to avoid "getting busted"
[1] edit: I'm the one who is mistaken, see frogpelt below. Leaving it up because I think it adds more to the conversation regarding the practice of police work as it relates to drugs and property seizure.
From the article you linked:
"Cooper says one mentor was Barry Washington, who is named in a class-action lawsuit that’s been filed against the city of Tenaha, Texas."
