The text of Florida SB1365 is here for any who wish to read it; it's fairly short: https://m.flsenate.gov/Session/Bill/2024/1365/BillText/er/PDF
As @Sawbonz pointed out, there is a push/pull aspect to this and for me, it is what is unwritten where things could easily go off the rails. For example, what is to stop a county from having a revolving carousel of migrating homeless people wherein the law (enforcement arm of the govt) drops off 'offenders' in another jurisdiction--I've heard this kind of happens now from rural to urban areas because rural areas lack social services, but I cannot vouchsafe for that rumor--which leads me to a different thought after perusing the bill/law: since counties/munis are on the hook for the land, services, etc and residents, business owners, and the AG can file civil suits (according to the bill lines 117-120) is another intended/unintended consequence to bankrupt these municipalities? I note this because a lot of the redress that a city (under financial difficulties) might have is regulated through the state (office of children and families) and seems like it would be possible to pick and choose whom to offer relief vs punish (cutting to the chase: blue county vs red county).
I agree that criminalizing homeless persons is not only troubling but an indictment on our society--all of us. However, I have no solutions to offer but that this one has some aspects that could be positive or abused and per usual the vague and airy waving of hands about the details probably ensures that Abbott will encourage the Texas Lege to adopt this and then go after Houston, Austin, et. al.
As I am not one of the Surly legal eagles, if anyone reads the signed document and has any thoughts to the above speculation, please offer them.
