Those two data points are not necessarily contradictory. Cop was dispatched to the scene because a guy was walking in the middle of the road (police chief’s report). He wasn’t sent there because of a robbery. But then as he gets there he gets the report about the robbery. If a store in the area was robbed the units in the area would have likely been notified

"Cop was dispatched to the scene because a guy was walking in the middle of the road (police chief’s report)."

I'm not sure he was dispatched to the scene because the two guys were walking in the road, but that he just happened to see them because he was already in the area.
