Time and delay is our best ally IMHO. Delay the bills and let the news cycle pass. I also think that in time we will see one of these mass shootings stopped by a CCW in a way that is hard for the media to ignore (Oregon) or water down (Appalachian State law school) and then the tide will turn. For now it will be hard to argue gun rights without appearing insensitive to the plight of the children. Using the argument that these shootings are just a part of american life won't get it either. We have to walk fine now as this incident is a possible game changer... to the bad.
