Remember, life in America is a paid privilege, not a right. You have no grounds to be anywhere unless you can pay for a place to be, whether temporary or permanent. And people who want you gone can't be arsed to make sure you are, in fact, gone before they destroy your place.
I will say that I support the workers' grievance that they should not be assigned to remove homeless camps since that is not in their job description nor are they trained for it. Making sure a place is really empty before you tear it up is a basic safety precaution, though. Checking boxes for occupants or potentially hazardous items is important.
