A review of the timeline:This is not democracy. This isn't even a Representative Republic. This is ruling by bureaucratic fiat.
January 2015: ATF published a new, OMB approved Regulation Guide stripping AR-15 "green-tip" from its armor piercing exemption list.
February 2015: ATF proposes a ban (which they've already put in place through their handbook published in January) on AR-15 "green-tip" ammunition and opens up a comment period.
March 16, 2015: The comment period about the proposed/already implemented ban on AR-15 "green-tip" ammunition closes, ATF ignores tens-of-thousands of comments because they were never going to consider them in the first place, and continues with the regulations outlined in the new 2014 Regulation Guide.
So are all the individuals that bought/sold this ammo after Jan now felons?
The ATF needs to have their funding reduced.
Here's the link to the guide. Pg 190
