Video of the arrest by Hong Kong police of a man who appeared to an American went viral Saturday as social media users publicized the violence that accompanied the 13th week of protests against Chinese overreach in the city.

“What charge is this? Otherwise it is unlawful!” shouted the man, wearing a T-shirt and cargo shorts, in one of several videos of his arrest at Lai King subway station during the demonstrations.

“This is Hong Kong, this is not China!” he said in a second clip that got wide distribution.

In that scene, he was surrounded by at least five Hong Kong cops in riot gear, who wrestled him to the ground as he repeatedly shouted, “Do you agree with the rule of law?” Police appeared to use a zip tie to restrain his hands behind his back.

The man was not identified, but spoke English with what sounds like an American accent. Some commented online that he sounded like he had been drinking.

A third video reportedly shot before the arrest shows the same man loudly talking with other passengers on a subway car.

“Why does Beijing want to hurt Hong Kong people?” he asks a young Hong Kong man. “I’ve been here 24 (expletive) years. Why do they want to hurt me?”

In a video posted on YouTube by the Epoch Times, the man insisted that China was subverting the rule of law by not honoring the “two systems” pledge made when Hong Kong was handed over by Britain in 1997 that promised Hong Kong “a high degree of autonomy.”

“They won’t let the Hong Kong people rule Hong Kong? That’s not a high degree of autonomy, that’s no autonomy!”
