What technique is used to maintain control over a suspect's arm during escort?

Using a firm grip on the elbow joint is a technique that provides better control over a suspect's movements during an escort. By holding the elbow, an officer can guide the suspect more effectively while also limiting their ability to resist or escape. This grip leverages the joint structure, allowing for a more manageable and safe escort, as it keeps the suspect's arm in a position that restricts sudden movements.

Additionally, controlling the elbow allows the officer to maintain balance and stability, which is crucial in situations where the suspect may attempt to pull away or turn suddenly. This technique is also less likely to cause injury compared to other methods of control, providing a balance between compliance and safety. Overall, it reinforces the officer's authority while ensuring the suspect is escorted in a secure manner.
