Amazon knows where their property line is, in the sense that the organization could locate it eventually given the need. However, just one person called the sheriff. Maybe they thought their property extended to the roadway, instead of only to the fence line?

In either case, it is basically a nothing-burger because the Sheriffs showed up and recognized their right to be where they were, and went on with their day. It seems like the system worked?

Feel free to attribute organizational motive to it through your own heuristics, but I expected a little bit better from a globally read newspaper.
