Thank you for posting this! This is truly horrible and it should have never happened. This is the type of stuff that makes people on the other side of the argument say "see, I told you assault weapons are bad." They won't even take the time to see what really happened or whom is to blame.
Actually I was watching some of the videos on C-Span and the talk is not about the firearms much. The Congress Committee is making sure its known that the firearm dealers were basically forced to sell the weapons by the ATF.
