My husband is a professional firefighter. Do you know why fire engines have big bumpers? To push cop cars out of the way. When cops respond first, they park in front of the structure, car, etc. This makes putting out a fire more difficult.
I believe it. My Dad (God rest his soul) was a volunteer fireman in our little community. They used the bumpers more than once to encourage people to get out of the way. Never the cops as far as I know but... I foresee there being lots of ways, subtle and not so subtle, for the firemen to express their displeasure with this cops' actions. It was a boneheaded egotistical play and he should get called on it.
