Some probably agree with Sarah Brady that the Second Amendment is "an anachronism." -- They probably didn't meam their oath to defend the Constituion -- they really intend to attack the Constitution.
When, & if, elected officals and law enforcement agencys attempt to implement such 'law', they will be violating their oaths to protect & defend the constitution. Unintended consequenses may arise.
You've probably heard the phrase, "truth always outlives a lie". I like to rephrase that to, "honesty outlives a lie". That's said, consider the dot-com bubble burst of 2000. Dozens of dot-com companies with PE ratios at 80 to 1 despite never showing a profit in any quarter were destined to crash. Some "lies" are bigger than others. It's generally a fact that the bigger the "lie" the harder the crash when honesty eventually illuminates the environment for what it is and what it is not.
Now consider the plethora unjust laws and illusions that have been foisted on the people depicting the government to be just about everything but what it is supposed to be -- not to mention that almost every high-ranking government official has violated their oath of office.
The fraudulent house of cards is on the verge of collapse. Considering the leviathan-government lie, the crash will be proportionate. People get desperate when the economy and markets tank. Especially when stock markets, real estate markets and job markets lose massive value -- trillions of dollars and jobs.
We live in a different age than the 1930's great depression. This time around governments will be illuminated as the problem and business/science/technology advancement the solution. It's well into the preliminary stage on the Internet. No status quo external authority is announcing this. Rather, millions of individuals around the world are beginning to make similar assessments via the internal authority of their own thinking/integrating processes.
Unintended consequences is honesty illuminating the lie.
