I’ve read a half dozen of these threads and I haven’t seen great evidence that the people are being held or denied their basic civil rights. AFAIK, they can leave. They are, by several accounts, being denied access to power for charging cell phones - boohoo. Generators are easily taxed and thoughtless people used to every convenience need to get real. Further, the complaints seem to be on the order of their menu complaint. What would people report if they were in any lockdown?
The problem here is that the camp operators are trying to prevent the problems in the camp from being reported to the outside world. That is wrong. And it appears to be the State of New Jersey doing it. Freedom of speech does include being able to use your cell phone. Lying about lack of power and unplugging charging phones is philosophically little different than the feds pulling the plug on FR.
