Are you justifying the neighbors actions?
That does justify the Deputy's action. His job is to remove her stuff from her landlord's house. His job is not to provide security for her stuff. That becomes purely and completely her problem. Had she paid her rent, there would be no problem.
For the record, it is a difficult and time intensive process to evict a tenant. She had plenty of warning that this was coming.
YES!
Her stuff was trash that SHE had already refused to remove. Her stuff was hauled out to the street as trash. Landlords and police agencies cannot be expected to take custody and preserve all trash that anyone wants to leave laying around until that want it back.
The neighbors are FREE to take some of the trash before it is hauled to a landfill.
