During this reign of the next president, it is expected that two supreme court justices will step down. With a decision of 5-4, and the possibility of a change in justices, I wouldn't be celebrating to heavy as of yet. It is a victory for those who want to defend themselves in places like DC, NY, San Fransisco and Chicago. Should this decision change and a activist justices get chosen who believe the Constitution is a "living document" that they can mold to fit their agendas or expectations, and they replace justices who interpret the Constitution as written, Tennessee laws can change through their decision. Even if we have 3 tiered government, activist judges can force federal legislature to amend that a state may be required to follow.
