Or, for short term political gain, another unenforceable law will be passed. IIRC North Carolina did for a time make it an offence to mention climate change in official documents. While ideology might have played a part, the real estate industry also has a vested industry in not scaring off potentials
mugs customers from sea-front properties in an area that is expected to see higher than average rises in sea level. Having no official docmentation mention the potential risks gave them plausible deniablilty.
But on a more practical level this could be used to incriminate just about anyone and lock them up while you look for something more substantial. US law enforcement agencies are already frequently overstepping the legal boundaries and though occasionally slapped down by the courts, are always on the lookout for more other reasons to detain people.
