I was in the CJ field for 10 years, which opened my eyes to a lot. I know you think "they're fascists who ignore the law" is reductionist or untrue, but that is literally it. It is that simple. It is also not new, regular law enforcement in the US has been exactly like this for pretty much our entire history.
When you break the law, and you have powerful deeply ingrained cultures and institutions backing you that will look away or refuse to apply the law to you, then the law effectively does not exist. Laws are social contracts that are invented entirely by us, and literally do not exist if not enforced. The universe does not care. There is no karmic balance that steps in to even things out.
I think many are just ignoring this or trying to rationalize it some other way, because it is terrifying to come to terms with when you are told your entire life that these institutions, police and courts and laws and checks and balances, are in place to protect you. Law enforcement in the US has fascism and nationalism baked into its core, and most of them are actively wanting what ICE is doing. Many law enforcement are in their ranks or are assisting in ways that most people don't even realize. And beyond that, the rest of our judicial and political systems are also being manipulated or just blatantly ignored to pave the way for this.
Ultimately the question being posed to the US at this point is, what happens when the people in power do not care or feel empathy, except for their own goals, and there is no sufficient opposition. There are no easy answers to this. When two opposing forces collide, one or the other has to give in some way. ICE has had basically zero consequences for their actions, despite how blatantly illegal and wrong they are. So far, their side is applying more force and it shows.
I've never used them so you'd need to research a bit as I only have experience with their gateways, but Unifi makes security equipment that I believe can run locally or be hosted to devices from your network
Maybe someone more knowledgeable than me can chime in if they have experience with their security ecosystem and how complex it is to use as you would a ring
