The problem is they (liberals) aren't changing their playbook. A shooting happens, be it Sandy Hook (which should have been their coup de grâce) or even in this latest shooting they will go after unrelated areas like high capacity magazines or modern sporting rifles. And show the intent of their true colors of banning entire classes regardless if they were used or not. So instead of going after the root causes (in this case the less than stellar response by the police and the mental health failing) they will stand yet again on "ban and restrict!" And fail, yet again.
The mental health issue is one that needs addressing. And one that was brought forward and supported by the NRA. Unfortunately, the left decided since the NRA thought of it first, it was automatically "bad." And the left leaning media portrayed the NRA as not backing the legislation they supported by distorting the facts. Any time you have riders in the bill that call for other things besides the original intent like the Manchin-Toomey bill, you're going to get push back.
If they left would just stop for a moment and attempt to work with Pro-2A groups like the NRA and GOA without uttering the word ban or putting in hidden language in their bills they might get a bit more headway. And stop standing on the still warm bodies of victims to proclaim their political agenda. And get educated in the facts about firearms. And actually have a reasonable debate with common sense (not Obama's common sense either) goals in mind. And actually stop demonizing groups like the NRA that actually stand for the lawful and safe use of firearms and teach same.
Maybe we could get somewhere.
