Boston - Just had a conversation with my son who is on the job in Boston. One of the firefighters in his house just had a heart attack almost in the rear of a BFD firehouse. He was off duty but lived near the firehouse. His father, who was with him, is a state trooper and immediately called it in as cardiac arrest and started CPR. It appears the Boston 911 system downgraded it from "cardiac arrest" to an "unknown medical" and, incredibally, cancelled the engine response which would have been 30 seconds away. The ambulance did not arrive for over 5 minutes plus.
