In medical law and medical ethics, the duty to protect is the responsibility of a mental health professional to protect patients and others from foreseeable harm.[1] If a client makes statements that suggest suicidal or homicidal ideation, the clinician has the responsibility to take steps to warn potential victims, and if necessary, initiate involuntary commitment.[2][page needed] The majority of people have, at some stage, had thoughts about killing someone, but the seriousness or intention of carrying out these thoughts may differ among persons and individual circumstances.[3]
