Ask yourself this question....the guy on the property...is not the owner...he is the renter.
This renter had no true profession....so where did the monthly rent money come from? Think about that a minute. Some charity group is backing him, and you can guess where this leads onto.

Women with children were there. I would not be surprised if they were getting welfare checks.
It sounds like they were squatters, not renters. Landlord-tenant law being what it is, and knowing that most states frown on self-help when it comes to evictions, I can surmise that these folks were hoping for relief from the sheriff without having to go to court.
