The AG is the high-profile guy, would be portrayed and pilloried by the MSM as persecuting these poor alphabets ...
Much easier, much MUCH smarter to re-invest the IG with the power that Bobo took away from him, and conduct all of these invest sotto voce, and with independent, trustworthy, NON-LEAKING IG staff, not the alphabets.
In fact, this latter approach is already reaping rewards.
The IG can’t prosecute or even reprimand anyone.
