"I am 100 percent innocent," the 20-year-old Long Island college student told reporters earlier this month. "I didn't do anything wrong. I was just there to videotape."
Civil liberties experts say Demint is part of a growing trend of citizen videographers getting arrested after trying to record police behavior.
