Police staffing has been going down since black lives matter became a thing. They dont get the same unquestioned respect and love like they used too so no one wants to be a cop any more. This one doesn’t give years but it says 5% over the last couple years. The change is bigger in larger more liberal cities. Chicago is down 13% since 2018 , san francisco which inspired this meme is down 20% since 2017 and all the mayoral candidates are falling over themselves to say they’ll solve it even though crime is down.
