Click on or copy the above link to view tools used by Police in China to control violent subjects. The first tool is a pole with a leg clamp on the end. By pressing the clamp onto the subjects leg, you can then pull , push or twist the pole to force the subject to the ground. The second tool is a long handle body fork that is used to pin a subject to the ground. These tools would appear to be very useful to gain control of the type of psychotic or drugged subject that may resist the effects of a tazer or pepper spray.
