Which of the following is NOT considered a Level 4 aggressive response technique?

The correct answer is the normal application of handcuffs because this technique does not fall under the category of aggressive response methods. In the context of response levels, Level 4 techniques are recognized as aggressive responses that may lead to significant physical harm or injury.

The application of handcuffs, when performed properly, is primarily a control technique aimed at restraining an individual to prevent further harm or escape without excessive force. It is typically employed in situations where an officer needs to ensure safety and manage a subject effectively, especially during an arrest or when maintaining perimeter security.

In contrast, techniques such as stuns, OC spray (oleoresin capsicum spray), and strikes/punches/kicks are considered more aggressive because they are intended to incapacitate a subject quickly and can potentially cause injury. These techniques are used in high-stress situations where an immediate and forceful response may be required to ensure officer safety or the safety of others.

Thus, the normal application of handcuffs is regarded as a necessary procedural tool rather than an aggressive response, making it the exception among the listed options.
