As clashes between protestors and police escalate in Hong Kong, protesters suspect some among them were undercover police. This photo of a "protestor" tossing a Molotov cocktail shows he also had a gun. Hong Kong citizens can't carry guns, but police can. Several protestors who incited violence had red LED lights on their backs, which most protesters didn't.
