We at ASA have two pilots awaiting trial for assault/battery on a gate agent. Both incidents happened in ATL and the gate agents "claim" the pilot either struck them or twisted their arm. Her friends at the gates next door (~50 yards away) "claim" they "sawed 'da whole thang".
My understanding is that the gate agents tried several times to get a monetary settlement in exchange for dropping the charges. The pilots elected to go to trial.
