Another legal victory for NY Jets wide receiver Robby Anderson ... who just beat the charges in his cop fighting case after other officers said they didn't see Anderson do ANYTHING wrong.
Anderson was arrested and charged with resisting an officer with violence when he allegedly got physical with a cop at the Rolling Loud music festival in Florida on May 7, 2017.
Officials say Anderson had backstage passes for the event -- but was denied access -- and a verbal altercation had broken out.
When cops arrived, Captain Ortiz claims Anderson was combative and pushed him .
