Control Holds & Restraints. Certain situations may arise where words alone does not reduce the aggression. Sometimes security guards and security officers will need to get involved physically. At this level, minimal force would involve the use of bare hands to guide, hold, and restrain. This does not include offensive moves such as punching, tackling, and choking. Pain compliance holds could apply here, but only after ordinary holds fail to control an aggressive suspect.
