Sounds like one of the mobile police stations we have down here in the Baltimore/DC area.
Looks very similar to a fire truck, but is actually an office on wheels. They use it for things like standoff situations, events, and other reasons
you'd need a near by place to handle information or communication.
For a while, the Baltimore one (they may have more) was just black. It had expendable com and camera towers and such. After about 8 months they
finally got around to painting the police logo on the side.
It may not be police, I know some companies have similar trucks.
