BATON ROUGE- A federal judge has dismissed a lawsuit that accuses Black Lives Matter and several movement leaders of inciting violence that led to a gunman's deadly ambush of law enforcement officers in Louisiana last year.

  

U.S. District Judge Brian Jackson's ruling Friday says a lawyer for a Baton Rouge sheriff's deputy wounded in the attack "utterly failed to state a plausible claim" and instead launched a "confused attack" against Black Lives Matter, activist DeRay Mckesson and others.

  

Jackson previously ruled Black Lives Matter is a social movement and therefore can't be sued. Last month, he threw out a separate lawsuit in which a Baton Rouge police officer blamed Black Lives Matter and Mckesson for injuries he sustained during a protest over a black man's shooting death during a struggle with police.
