The department deleted the above tweet shortly after posting and decided to honor Bill Russell instead. You could actually see the wheels turning in real time with the realization that a completely unforced error had been made and needed to be addressed.
The clean-up effort included an apology to those offended.
It may not surprise you to learn that this gave rise to a backlash to the backlash from those who believe the department should have left the Auerbach tweet up.
Another productive day on the internet, as they all are.
