I was right there. The detective was riding this scooter *through* the crowd. When I first saw him I was like 'what crazy right-wing nutjob got through the police to do this?' People were trying to pull him off the bike to *stop* him from hurting anyone else - which I also would have been doing if I was any closer. I had no idea he was a cop. The only time I began to realize it was when he appeared to be reaching for a weapon on his left side, and then it dawned on me that he was a totally freaked out undercover who was just a hair away from possibly killing someone. NYPD is lucky no one got killed just then, and it would have been their fault for allowing a totally reckless motorscooter charge through a crowd by unmarked police. What the hell were they thinking?
