Walking Dead star Chad Coleman has apologized after being videotaped going on a tirade against his fellow passengers while riding the New York City subway. “Where my humanitarians are?” the actor yelled during the bizarre three-minute outburst, caught on a passenger’s cellphone. Pacing back and forth on the subway car, Coleman continued, “Yes! I’m Chad L. Coleman! I’m on The Wire, The Walking Dead. I’m not trying to play no f—ing games with you. Where is your humanitarian?! Don’t tell me I’m making this up!” Coleman has denied he was drunk during the diatribe, which he said was triggered by “built-up frustration” over the death of Freddie Gray in Baltimore and the use of the N-word by a fellow passenger.
