Point by point:

1. Gun control proponents' interpretation of the Second Amendment must prevail at all costs.
2. Columbine had nothing to do with the issue of concealed carry.  Colorado's CHP laws are in line with 44 other states (either "shall issue" or "Constitutional Carry").
3. The silencer/suppressor bill may, indeed, return, and Congress will decide it's fate, as it should be.  As for other "NRA-desired perks," you'll have to be a little more specific.
4. Republicans and Democrats, alike, have a responsibility to address the shortcomings of our mental health system.  BOTH parties have failed in this regard.
5. I think the prohibition of automatic weapons is appropriate, and I would support a law banning devices designed to circumvent that prohibition.
6. We have an entirely different history than "most industrialized nations."  Not enough room to expound on that in this limited format... I'd love to discuss it over coffee sometime if there was a way.
