Would it expedite the cooling if fire departments had sacks of crushed

Probably not. If you assume they can maintain typical freezer temperature
of -10 °F, that's still only ~80 °F away from ambient temperature.
Not that it is significant, but you have ignored the "heat of fusion".
Ice soaks up much more heat in that last thawing degree.
