Black terror: The real threat to freedom in Hong Kong

Cyberspace has become their "on-line black territory" as well.

Toby Gu, a Canadian vlogger who posted a video of black-clad mobs beating a passerby on YouTube, has received death threats.

Having read much news on Hong Kong, he decided to fly here, expecting to see the "peaceful" protesters and "brutal" police.

What he saw was just the opposite -- brutal protesters and restrained police.

He captured footage of a man being savagely and relentlessly beaten by rioters. A large mob swarmed on the man, raining a storm of fists and kicks on him.

What did the man do to deserve the savage beating? Video shows his hand brushing over a leaflet protesters had stuck on a wall in a metro station. Covered in blood and bruises, the man was cornered in the metro station while rioters continuously hit him in the five-minute video.
