Because Second Amendment abridgment epically failed in congress, the President is taking steps to sidestep them:
Biden is unveiling two new steps President Barack Obama is taking on gun violence. The executive actions don't require approval from Congress, where gun legislation collapsed earlier this year.
One new step will curb the import of military surplus weapons. The Obama administration is also proposing to close a loophole that lets certain weapons be registered to corporations without background checks.
No mention as to how this will negatively impact the administration's Fast and Furious gun-running across the Mexican border (or, rumored, Libyan border). The majority of crimes where firearms are used aren't with military-issue fully automatic firearms and they aren't committed by individuals who've registered them with corporations. It's all moot, anyway, because if a criminal is disallowed by law to possess a firearm in his or her state, no law regulating registration or additional background checks is going to deter a criminal from breaking additional laws after breaking the first of unlawful possession.
By enacting this, the administration solves nothing, unless, again, this is a Rube Goldberg-esque way of banning their own previously mentioned programs. This administration by itself could use a little gun control.
