For those of you who were not here when this happened: The police decided not to respond the actual 911 calls in or _near_ the CHOP (the auto shop was a block _away_, not within) was a retaliatory tactic they employed out of spite. Knowing full and well that it would look bad on the protesters and those who created the CHOP. Denying health services and aide is NOT what people who are advocating for defunding the police are advocating for.
I agree, this is absolutely a straw-man argument.
