Just came across this case where a California Highway Patrol officer tried to arrest a firefighter in the midst of treating people injured in a traffic incident, simply because he refused to move a fire engine that was blocking a lane of traffic on the highway to protect first responders and the patients they were attending to.
My favorite firefighter fact is that they will straight up use their trucks to shove cop cars out of the way, and if they get smashed to shot, oh well.
