From the PDI Editorial:
TWO OF THE MOST FORMIDABLE, IF NOT intimidating, lawyers in the Senate took turns trying to beat Vidal Doble’s credibility (arguably shaky at best, to start with) to a pulp. Sen. Joker Arroyo tried to point out the contradictions between Doble’s past testimony and the version he gave the Senate. Arroyo seemed eager to spotlight Doble’s having had a civilian lawyer, which would suggest that the testimony was beyond military pressure—until Doble pointed out that his civilian lawyer was provided by the Philippine National Police.
Sen. Juan Ponce Enrile focused on Doble’s habeas corpus petition filed with the Court of Appeals, a document prepared by opposition-affiliated lawyers. Doble, however, revealed that he had been reminded, before he testified, that the long and short of whatever he said was that he remained under the authority of his unit, the Intelligence Service of the AFP. So, Doble said, with that pointed reminder still ringing in his ears, he lied.
Instead of demolishing Doble’s credibility, Arroyo and Enrile simply clarified the tremendous pressure—Doble himself bluntly said it was duress—that tainted not his latest, but his previous, testimony.
Arroyo and Enrile—as unlikely a pair of comrades-in-interest we would ever hope to find, but politics indeed makes for strange bedfellows—had to retreat with obviously ruffled feathers, in the manner of Estelito Mendoza and his confrontation with Clarissa Ocampo. We are far from saying that Doble is an Ocampo. But the way he stood his ground, and made a shambles of the two senators’ virtual cross-examinations, is a comparable demonstration of how a witness, instead of being impeached, can impeach the prosecutors.
There's more. Read the whole thing, especially re Medy Poblador.
