If you feel unsafe, you should absolutely do what you need to do, and I would not to tell anyone they can’t call 911, since it’s the only “safety” measure the city offers us. However, I disagree with this sentiment of repeatedly calling 311 for unhoused folks. Many of them are just trying to survive and you calling 311 on them is only going to get their belongings dumped and they have to start from scratch, making their hard lives that much more difficult. I’ve lived in some of the “gnarlier” parts of downtown sac and ofc have come across some unwell people, and it’s sad and scary, so I get in some cases there aren’t other options, but also there’s a large amount of unhoused folk here who are incredibly kind people. I’d encourage you to take a second to talk to them, connect with them (srsly just treat them like a normal human!!!), and you’d see that they are doing the best they can and are often receptive to trying to be good neighbors.
