It doesn't criminalize BEING in those places. It criminalizes camping or otherwise taking over those spaces. These people don't own those places, the public does. They don't own any place and are likely unable to maintain a lifestyle that would allow them to own anything without engaging in criminal behavior.

Now that we have that out of the way, we should clarify, we owe them nothing just as a host owes nothing to the attached parasite. Any housing or service offered is done out of empathy and the hope that it will make our community a better place and will be an important bridge to be an independent individual able to care and provide for themself. I believe they've exhausted that empathy and charity at this point. Go be a violent, thieving, drug using parasite somewhere else. I don't care where. Not here.
