Who knows how many decades will pass until all of this will be properly challenged at the Supreme Court. It's why I've argued here in the past about US' necessity to create a "Constitutional Court" that wouldn't allow blatantly unconstitutional laws to become laws after Congress and the president pass them in their effort to gain more power and control over the population.
