Yup they just don't want to be on video destroying people's lives. They know this is wrong. They feel shame, but they're doing it anyways. So the last thing they want is video evidence they were ever this cruel.
Consequences. Because once you understand that for profit housing is the root cause of homelessness and not some vague unwillingness to live indoors then homeless people are victims not criminals. And if we ever get this country to actually be worker centric instead of owner centric we're going to look at those videos and identify the people willing to punch down on victims. They don't want that, and they especially don't want people seeing them haul senior citizens off to prison because they didn't comply with the destruction of everything that won't fit into a duffel bag.
