About ten years ago I was talking with a Group Supervisor. He told me that he was seeing an alarming trend of hiring and promoting special agents with strong bodies and weak minds. It seemed amusing at the time. I thought "No way!". Surely we have learned from our mistakes.
However, Retiredwithintegrity made an astute observation that ATF/DOJ is using "training" to indoctrinate Yes-Men. The new Agents may never see the big picture; they will know "what", but will not know "why".
