When can using chemical weapons be regarded as unreasonable?

Using chemical weapons can be regarded as unreasonable when employed on someone who is already subdued. This is because the purpose of chemical weapons, like any type of force, is to gain control over an individual who poses an immediate threat or is actively resisting arrest. Once a subject is subdued, the rationale for escalating to such forceful measures is lost; it may be deemed excessive and unnecessary.

Engaging in the use of chemical agents against someone no longer posing a threat not only undermines the principles of proportionality and necessity in law enforcement but also can lead to severe legal repercussions, including accusations of excessive force or abuse of authority.

In scenarios involving compliant or subdued individuals, officers are expected to utilize de-escalation techniques and proportional responses rather than resorting to means intended for high-risk situations.
