Sleeping dragon (manoeuver)

A series of protesters are handcuffed together through PVC pipe, which prevents police from simply using bolt cutters to break the handcuffs.

Advanced variations include covering the PVC pipe with elements which might make it more difficult to break.

Often the protesters will chain, lock, or otherwise secure themselves to immovable objects, resulting in a difficult-to-remove human obstacle.

[2] Officers may put fire retardant hoods and earmuffs on the protesters to protect them from sparks and noise as tools are used to cut through the sleeping dragon.

[3] Once an inspection hole has been made, it may be possible to reach in with bolt cutters and cut the handcuff chain.
