Q: 1. Why is it sometimes necessary to rotate the key in the reverse direction at a certain angle when opening a double lock?
A: This is a precise manifestation of the double-lock mechanism. Rotating the key forward unlocks the lock; when the double-lock function is activated (i.e., the ratchet is locked), an additional locking pin inside the lock cylinder jams the mechanism. At this point, the key needs to be slightly rotated in the reverse direction (usually accompanied by a soft click) to release this locking pin before continuing to rotate it forward to complete the unlocking process. This design significantly increases the difficulty of technically unlocking the lock.
Q: 2. What are the standard tactics for shackles on an extremely uncooperative or struggling suspect?
A: This is a high-risk, high-skill tactic, typically following the "control-stabilize-handcuff" principle:
• Team Control: Requires at least 2-3 law enforcement officers. First, use limb control techniques (such as joint locks and pressure point control) to subdue the suspect to the ground, placing them in a prone or side-lying position.
• Stabilizing Position: One person controls the upper body and arms, while another focuses on the legs. Cross-control the target's ankles.
• Safe Operation: The operator approaches from behind the heel, quickly slips and locks one side of the handcuff, then immediately controls the other ankle to complete the handcuffing. Throughout the process, avoid placing yourself within the suspect's kicking range.
• Core Principle: Never attempt to handcuff while the suspect's legs are still able to exert force freely.
