This No Hat Cop meets the Gordon Arnold description that has been laughed at to this point for decades. DPD dress, No Hat, Sunglasses, and short cropped hair. And if we are now down to claiming that the Sun is reflecting off of cloth, then I'm guessing that Arnold is smiling down. Take a look at ALL the crowd scenes inside Dealey Plaza on 11/22/63 and find a John Q. Public dressed like this No Hat Cop. That DPD "look" is unique and intended to intimidate. John Q. ain't buying threads like this.
