ok so based on the article, the police respond to over 25k mental health events annually, and over 17 years, 40 people have been killed.  So that's a 0.009% rate over 17 years.  Seems to me that all of this extra training money could actually be put into the mental health system where it would do more good to address the 25k events rather than the 2 on average that end in tragedy.
