The tone of privilege, yes, but also the almost willful naiveté. He talks about serving in Afghanistan and other trouble spots, yet wants to claim he was operating in a state of shock because he saw someone who flipped off a bike.

Get angry with the cops for abusing their authority, sure, but the "I couldn't believe what was happening" attitude comes off as forced.

No, I'm not blaming the victim or excusing the cops. What he did in the moment might have been perfectly reasonable. But to write it the way he did after the fact rings slightly hollow to me.
