[2] Tools such as a whip, a baton, an electroshock weapon, or use chemicals such as tear gas or pepper spray are commonly used as well.
[5] In disciplined law enforcement, the use of pain compliance forms part of a use of force continuum which will usually start with verbal warnings, before escalating measures.
[citation needed] Another common use of this technique is to physically compel chosen behavior, e.g. curbing school-yard bullying or racketeering, independent of any law enforcement process.
[7] Pain compliance as part of an escalation of force policy normally presumes a rational adversary, but some altered states such as mental illness, phencyclidine and amphetamine use, or extreme adrenaline may alter the subject's perception of pain or willingness to submit.
For this reason the use of pain compliance is often subject to explicit rules of engagement designed to prevent abuse and avoid conflict escalation.
