But he appears over-restrained, to the point of inaction.

For damned good reasons - he's the top law enforcement official in the land. The only people more powerful is the President, and the Supreme Court. He has specific and clear legal reasons to stay in very carefully chosen lanes. He has to follow rules and laws, chasing people who disregard them. Crime is fast, catching, trying, and convicting them takes time. And, with the microscope he's under with the press and openly hostile political party, everything he says has potential for more lawsuits, attacks on him and the rule of law, and the process of defending the law. His every day is walking a minefield. That's why i think previous AGs like Janet Reno should have been investigated and jailed, because they abused the power that they held. Reno should be in jail for Waco, alone.
