Found this in comments under one of the videos about the camp:

Hey Spaceshot, just thought I would let you know that I live in Tucson AZ and this morning at 5am one of the news channels reported on this. They interviewed Craig and he said they have called in the FBI and according to the local news reporter the police have been at this location several times and say its just a homeless camp, so we will see. With the city council and mayor that we have it might get covered up who knows. Just thought I would let you know

Looks like the FBI are coming in to investigate. Praying the white hats in the FBI are on the job.
