Not sure why Adelanto cops were there. Perhaps an arrangement with the San Bernardino sheriff who must be spread pretty thin over their giant county.
However the camp ground was closer to Victorville which must have a much larger police force. Why didn't they respond?
UPDATE - there are no Victorville cops, they contract the sheriff.
Another update to the above - there are no Apple Valley cops either. They contract the Sheriff.
Not sure why little Adalento has it’s own police force though.
