Good points. Perhaps lowering the dosage would give the officers some safety and time. The idea of mild sedation beats violent force used on someone who is sick and out of control.
to be honest, no, sedation on a patient with unknown possible previsous medication ingestion, is not better than manhandling.
Best plan? take care of these people inpatient. Bring back long term mental hosptials.
Teach emergency providers and LEOs how to manage out of control patients. Hell hospitals do it with 100 pound aides.
