IG report critical of "Operation Gunrunner"
Story here. It does repeat the false mantra that "80 percent" of guns confiscated in Mexico come from the US. But it notes that ATFE does not cooperate or share intel with ICE, and ATFE tracing operations in Mexico get little cooperation with ATFE in the US, and supervisors pushing small investigations that can be completed quickly rather than larger ones.
Needless to say, the agency says that if it just had more money and laws it wouldn't be incompetent: "One senior ATF official, who spoke on condition of anonymity, said that many of the problems identified in the report stem from a lack of funding from Congress and weak U.S. gun laws, including the absence of a specific statute making weapons trafficking a federal crime."
UPDATE: yes, the "we need another law" excuse is especially lame, since it's already illegal to export firearms without permission, to engage in the business of dealing in firearms without a license, to transfer guns to a nonresident of your State, to transfer guns having reason to believe they would be used in crime, etc., etc..
