I’d be interested in what the lease agreements for these various private homes and businesses on public land say.
Supposedly we’re a nation of laws. If the lease allows for these places to be shutdown in this sort of situation, then the owners should comply, since they agreed to what is in the lease. If not, the response is “get a warrant” (although for what, I’m not sure). Barring that, any entry is trespassing and/or home invasion and should be dealt with accordingly.
I posed that question in another thread. And what about the leases for the homes on Federal land that people live in? They have been kicking them out too.
