SANTA ANA, Calif. (CN) — A defense attorney for the Mongol Nation motorcycle club told a California jury Tuesday that federal prosecutors had not presented any evidence that the club ever violated racketeering laws or engaged in a conspiracy — indeed, he said, it could not be convicted of conspiracy because an entity cannot conspire with itself.

“There’s no evidence that the Mongol Nation conspired to do anything,” Joseph A. Yanny told the Orange County jury in his closing arguments.

“There are individual members” who have committed crimes, he acknowledged, but “there’s no evidence at all that the club joined in those activities.”

He said the club itself cannot be held liable for “isolated incidents committed by boneheads.”

A federal prosecutor Monday told jurors who were “witnesses to a lengthy parade of cruelty” for the past five weeks in a trial against a Los Angeles-based motorcycle club that they should vote to yank Mongol Nation’s trademark while the organization’s attorney argued it has been targeted because its membership is primarily Mexican-American.

“Over the past five weeks you’ve been witness to a lengthy parade of cruelty,” Assistant U.S. Attorney Steven Welk said of the evidence presented of the club’s criminal history since its founding in 1969.

For the first time, federal prosecutors are trying to get a motorcycle club found guilty of racketeering and conspiracy to commit racketeering in order to have its trademark taken away. It would mean the club’s motorcyclists could no longer wear the patches they wear on their “cuts,” slang for leather jackets.
