Uhhhh yes indeed the NRA is the sole problem here. It's a sales lobby group that has ridiculous influence in Congress and has blocked all gun violence research and passed laws making it illegal to hold someone accountable for putting a gun into the "wrong" hands.  They've convinced Americans that the inanimate object, the sale of which puts money directly into their coffers, is more important than living, breathing beings.

That's the problem. 
Make no mistake.
