Towing<br>Last week we saw a police car in front of a parked car. The car was parked in front of a fire hydrant. A tow truck tried to get the car but it was blocked in. The company called in a flatbed tow truck. Before they could tow the car the driver came and drove away.
The tow truck wasn't going to tow the police car.
