In the United States, Law Enforcement Assisted Diversion (LEAD) is a pre-booking diversion model that provides police with an alternative to criminal prosecution in cases involving low-level crimes related to drug use, mental health issues, and poverty. The multi-agency approach allows police officers to refer individuals to behavioral health services rather than arrest them. The model was developed in Seattle, Washington, where a pilot program was launched in 2011. LEAD programs have since been adopted nationally in the US.
