The number 5150 is a police code used when calling for assistance because someone is going absolutely insane.
It applies when the offender is behaving in a crazy manner due to mental illness or substance abuse.
The offender will often be on a psychotic spree and is rarely aware of what he is doing, where he is, and have a warped perception of reality.
He or she is a danger to themselves, others or to property.
In this case, the person can be detained for 72 hours in a psychiatric ward, and rather than focus on punishment and law enforcement, they are surrounded by nurses, psychiatrists and doctors.
