In docs obtained by TMZ, Meek calls BS on the allegation his murderous lyrics incited the violence. Live Nation, which runs the Oakdale, is also being sued -- claims the victim's family has stooped to racial stereotypes by calling the fans "thugs."
As we reported ... a hail of bullets killed 2 and injured 2 outside the Oakdale Theatre.
The plaintiff's attorney, Joel Faxon, tells TMZ he's confident "the families of those shot at the concert agree Mr. Mill meets the definition of a thug." He also said Meek owes concertgoers a duty to provide a safe concert experience and warn them of past violence at his events.
