Yesterday, I reported that numerous people believed that they knew the identity of the person who appears in this video, purportedly kicking a restrained protester: They believe the person on the tape is Wharton student Scott Robinson, who interned in Washington, D.C. this summer. At this point eight of them, seven D.C. interns and a University of Pennsylvania political science student who says he lived across the hall from Robinson for a year, have provided comments for attribution, claiming to be certain the person on the convention video is the student and intern they know. (Various others have sent anonymous statements to myself and other bloggers to similar effect.)
On Thursday evening (technically very early Friday), I spoke with Robinson. He conceded that he was in New York at the time, volunteering at the Republican National Convention, but says that he was not at the Andy Card speech where the incident took place around noon that Wednesday. He said he had been out late Tuesday night and didn't wake up before midday, as he was only working evenings. He also gave me the name of the Wharton fraternity brother with whom he stayed that week, with whom he said he'd been at the time of the Card event. That person, whose name I'm omitting at his request, declined to say anything on the record when contacted via email.
Update: The University of Pennsylvania's campus paper has picked up the story, with a comments section where students are discussing it. That piece adds a visual ID from the chair of the UPenn College Republicans, though a more tentative one than other sources have given. No further word from Robinson himself as yet.
