The nature of the job of AG is practically invisible. It’s a behind the scenes job until something is ready for disposition.
A critical point so many seem to be missing these days. Some want an AG holding daily briefing, spitting and fuming and pounding the podium. Ideally, the only time the AG would be before the press would be to announce the results of a concluded investigation, or to give brief progress reports that don't compromise anything on known, ongoing investigations.
In normal times I would be inclined to agree with you. However, extremely serious breeches of security have occurred during the Obama administration that have endangered our national security. The FBI itself needs to be reformed after having been politicized by Obama. Moreover, uncontrolled immigration is yet another crisis that urgently needs to be addressed before it destroys our social fabric.
Not expecting Sessions to fix everything over night but he needs to reassure the American people that the DOJ is not going to stand by and allow such crimes and scandals to go unpunished. We need that reassurance after eight years of corruption and witnessing government resources being used against law abiding citizens.
You may disagree, but I believe that people are anxious about our future and need to see that we are still a country of laws. For that reason, and because the DOJ is riddled with Obama loyalists, Sessions has to step forward and be a leader.
His senate days are behind him and he is in a new role at a critical point in time. Real leaders rise to the occasion.
