In Tennessee, a bill was drafted for consideration that denounced hate and discrimination in general and "white nationalist and neo-Nazi groups" in particular.
It went further to request those groups be designated as terrorist organizations.
... we urge law enforcement to recognize these white nationalist and neo-Nazi groups as terrorist organizations ...
The Patriot Act defined, rather broadly, the definition of terrorism and outlined additional powers law enforcement had to investigate potential terrorists and terrorist groups.
The question is, if the Tennessee bill had been signed into law how would neo-Nazi groups have been affected from a Constitutional rights perspective? As examples, would the group be unable to 'advertise' their rallies? Would individuals in the group lose their freedom of speech, 4th amendment right to privacy, or any other rights?
