This whole crack down on the Dutertes is just railroading of political enemies. They're not going to go after corruption among their ranks like Romualdez and now Enrile. This is one thing that idiot attention whore Barzaga is correct at.
It's no different from when the elder Duterte was in power and set his sights on Aquino, Leni, De Lima, Trillanes, et. al. Or Noynoy going after Arroyo while shielding his allies from persecution during the PDAF Scandal.
