Actually my bet is to the next time a mass shootings incident happens under a democratic president this will be the inevitable reaction.
That is interesting. According to ICE about 1800 people in the US have been killed by illegal immigrants. And according to the CDC 39,773 Americans were killed by firearms. So if this is a national emergency, what happens with 22 times the number of deaths attributed to something killing Americans? Could a national emergency be declared that people still have the right to firearms less deadly than a pellet gun only?
Same could be said on the effects of climate change on weather, backed by scientific data. That's a much higher death toll as well. Should a national emergency be declared to fund renewable energy and shutter coal?
Lung Cancer kills 300k a year. Should cigarette sales be a national emergency to shut them down?
Diabetes and heart disease are hundreds of times more deadly than this emergency, should a national emergency limit sales of red meat and shut down the soda industry?
Lack of healthcare kills hundreds of thousands of Americans. Should a national emergency be declared to completely socialize healthcare.
White Supremacists accounted for the majority of extremist killings the past 15 years. Should those groups be banned under a national emergency, and anyone supporting them be locked up?
It's an interesting box of worms to try and open.
