Recall the People’s Republic of China’s use of tanks to suppress the Tiananmen Square protests that resulted in some 2,000 civilian deaths.

Here’s the PRC’s new anti-protest armor: truncheons.  With the official police standing around, watching:

Media in Hong Kong have released footage of masked men in white shirts beating black-clad protesters with steel pipes and wooden poles in a subway station and on public transit. The protesters attempted to defend themselves with umbrellas.
Passengers said police did not intervene in Sunday’s attacks by the men, which left 45 people injured.

Forty-five injured by those truncheon-wielders.  Notice, too, that the thugs were masked, but the protestors were not afraid to show their faces.

Were the masks to conceal their Beijing origin?  The opposition party in Hong Kong, the Democratic Party, is taking (publicly, at least) a more generous position.  It’s investigating

the attacks amid suspicion that they involved the triad, a Chinese organized crime group.

I’m not so sanguine; although I don’t discount the idea that, rather than being sent by PRC President Xi Jinping’s supporters from the mainland, Xi caused the triad to be hired for the strong-arming.
