Don't listen to me, listen to Senator Charles Grassley, and the people who did the actual investigative reporting.
Both the “sting operation” and the ‘more gun control” are cover stories.
Both of these stories pacify the left and the “more gun control” gives the right something they want to believe so they don't look any further.
I'm giving you some advise, before blindly accepting the “more gun control” story you better dig a little further.
