Does anyone know of a movie scene that involves drugs/alcohol, mental illness & criminal activity?

I need to give a presentation on dual diagnosis & criminal activity so I need a movie scene in which someone behaves criminally- robbing a bank, committing manslaughter etc. as a result of mental health problems AND substance abuse. It doesn't have to be an identifiable mental illness but there should be something. Sub. abuse can be drugs, alcohol etc. Any suggestions are greatly appreciated! Thanks!
