There is a lot of evidence to support this story. I has also come out in the last week or so that the firearms dealer in Texas that is the most often traced to in the "Mexican Gun Traces" had brought concerns to the ATF on sales, including sales of multiple guns to hispanics that had questionable ID. They were instructed to complete the sales and continue selling to these individuals by the ATF.
If one doesn't have knowledge of an investigation then one would not be in violation. If he has knowledge of the investigation then he is hampering the investigation by talking about it.What came first, chicken or egg?
I fail to see what any of this has to do with the NRA. Could you explain you line of thinking there?
