If you haven't been following it, the ATF is catching hell for an operation they conducted where the allowed guns to flow into Mexico, hoping to identify top-level trafficers. As they let those guns get into Mexico, they also noted an up-tick in the violent crime rate. What else would they suspect might happen?
Two of those guns were used in the murder of a Border Patrol Agent.
Now, legislators in Mexico are demanding answers.
The ATF is an agency that deserves a severe slapping. The very idea of breaking the law to enforce it is anathema to good law enforcement. Everyone involved should be fired immediately and the US attorney with jurisdiction should proffer indictments.
