I'm gonna go with: don't send cops on welfare checks. Send somebody competent to respond to mental health challenges, preferably someone not wearing a police uniform (after all, at this point a lot of folks think "unaccountable killer" when they see that uniform and there's honestly reason for that).
Maybe they should have borrowed corporate lingo to call for right-sizing police, or restructure community resources.
"Defund the police" is such obviously bad marketing that it makes you wonder if the people who coined the phrase were trying to help or hinder reform efforts.
