YouTube video of Tokyo Police using excessive force to subdue a Non-Japanese in public

Al: In the wake of the case of Mr. Suraj, the Ghanian who was killed by Japanese immigration during a botched deportation, I’d like to share a video of clear use-of-excessive-force by Tokyo police on NJ [video]. Though we don’t know what the NJ did or how they took him to the ground, clearly he is already on the ground, subdued with 3 officers on top of him.

The disturbing part is the officer who is sitting on his lower back, applying unnecessary and excessive pressure to bend his spine. Why was this necessary?? He’s already on the ground, with his hands behind his back, and poses no threat to any of the officers. He’s clearly in a lot of pain, which shows in his voice. The officer sitting on his lower back could have simply just pinned his legs to the ground rather than bending his spine the way he does in the video. The officers are from Tokyo as can be seen by the 「警視庁」emblem on their uniforms.

Please get this video out as it is a disturbing case of excessive use-of-force on an NJ. Additionally, I find that use-of-force by Japanese police tends to be very arbitrary, without any clear goal or regulating doctrine. I myself have had my arms grabbed and pulled out of a department store for an ID check.
