I like to look at these situations on a more common sense level.
When an offender is challenging an officer, there is a general response to this behavior.
1. Verbal instructions to seek compliance.
2. If verbal instruction does not work (and this depends on your departmental or unit standards):
- Contact a supervisor
- Attempt physical compliance techniques
- Gas
THIS IS IMPORTANT . . . Concerning an attempt at physical compliance . . . if you cannot perform this on your own (due to size, abitlity, training), get help from other staff. If possible, always make sure you have the advantage.
As pointed out by other posters, the situation will also dictate what steps to take. For example, I wouldn't gas the visitation room with lawyers and family members present. I would use all attempts at Non-Violent Crisis Intervention here prior to proceeding towards physical force.
