Can security guards put someone into a choke hold?

Security guards generally do not have the authority to use choke holds or other potentially lethal force unless they are trained law enforcement officers and it is necessary for self-defense or to prevent serious harm. Most security personnel are trained to use de-escalation techniques and restraint methods that prioritize safety for both themselves and the individuals they are dealing with. The use of choke holds can lead to serious legal and ethical implications, so it is typically discouraged in the security profession. Always check local laws and regulations regarding the use of force by security personnel.
