While performing his duties a police officer may frequently be confronted with the behavior of an individual which threatens or has resulted in self-inflicted injury, or which poses an imminent threat to the safety of others. Under such circumstances an officer may determine that criminal arrest is inappropriate but that some form of restraint is necessary. Michigan has provided an alternative course of action by authorizing temporary emergency psychiatric detention of an individual whom a police officer deems to be "mentally ill and manifesting homicidal or other dangerous tendencies."
