I thought Hillary was also publicly pushing the 90% gun thing.....She started that figure rolling. And she started rolling after about two years after Wide Receiver concluded that “There is NO iron pipeline from the US to Mexico”.
I have little doubt those arms were sent to destabilize the Constitutional government there, and then expected to trickle up north...
I also have little doubt that she knew the data for the talking point were being generated over at the DOJ. Gun Control has always been high on her wish list.
It remains the stealth reason for Nationalized Health Insurance (It isn't Health Care!!!!), to price gun ownership right out of the park.
