In the New York Times this morning, Jim Dwyer revisits a police roundup of protesters that occurred during the 2004 Republican National Convention and notes that videotapes flatly contradict the police’s account of what happened. You can watch the video yourself, and hear one police officer tell two young women that it’s okay to hold up a banner, and then watch other officers arrest the women for doing just that, seconds later. For what it’s worth, I happened to be there that day, and wrote an account of it at the time.
