The way it usually happens. They call the attending physician if there is one (in this case there was a doc of record) and the JP talked to the responding LEO
That is usually all that happens
Take Scalia’s name and change it to Smith this would have been handled the same way.
JP did not talk to LEO, the County Judge did. But more to the point: this is not John Smith private citizen, this is Antonin Scalia, Associate Justice of the Supreme Court of the United States.
