They grill Manti, and not the others, because (1) the Manti story is infinitely larger on a national scale, permeating "regular" news and late-night comedy shows, so the media attention whores know such questions will attract much larger interest, and (2) they know Manti is too decent to haul off and kick their collective asses in response, whereas they have no such assurance with the "police blotter" crowd.
