Iirc that clip was posted by some Fa Lun Gong cultists and it blew up in their faces pretty bad. Makes me wonder how out of touch they are with Western society that they thought cops putting themselves at risk to non-violently apprehend an armed person was an own against China.

It's also quite common to see cops with man catchers or staves all across East Asia. Very effective tools, but it takes a lot of training and coordination to use well.
