It's not just "this" incident and it's definitely not directly related to hunger or poverty. You see this reported all the time in the bay area, they walk in and fill up carts with the most expensive shit in these stores and walk out with it in front of God and everyone.
My wife worked at a local Safeway down there and saw this happen daily as well, the employees are told to just let it happen and not to "bother" the police when they witness it because they won't even show up. Then you see people selling these goods online Craigslist, Nextdoor, etc., this is why most stores now refuse to stock expensive items on shelves now. I'm the first to go to bat for those being oppressed but it has nothing to do with this directly.
Nobody, no matter how liberal, would ever say "feel free to walk in and rob a store blind" with zero consequences. The losses to many of these stores in San Francisco have
forced them to close as a result.
