And why is the Tiahrt Amendment in place again?

Oh Right.

"Cardozo said there was one telling statistic that shows how some "very modest steps" would help stem the "onslaught" of illegal guns into New York City: 52 percent of illegal guns can be traced back to only 1.2 percent of gun retailers."

Obviously he didn't read the CRS report either:

"At the same time, ATF’s findings might have undergirded the policies of a number of municipalities, under which civil lawsuits were pursued against the gun industry for gun violence in their jurisdictions. This is despite the fact that ATF has consistently
stated that trace frequency, in and of itself, is not indicative of criminal activity by an FFL."

As Kim duToit occasionally says: Lawyer, Tree, Rope. Some assembly required.
