Not sure how you missed this because it was pretty plain. Oh well:

One of Colorado's 2013 laws allows the courts to prohibit gun ownership for people facing pending domestic violence charges, as well as those convicted of them. This closes an odd loophole in a similar federal law that only applies to married couples. I'm proposing we update the federal law to include all domestic violence offenders, & that we actually enforce it. 

That law certainly should have applied in this case (at least as far as I can tell). I can only assume he didn't lose his guns because it was a military conviction and it slipped through the cracks. Reform of enforcement is as important as reforming the regulations themselves. The goal should always be to infringe on the right as little as possible while still doing everything we can to prevent guns from getting into the hands of people who shouldn't have them.
