Psychics? Where the fuck are ya?

Much as the whole Madeleine McCann thing bothers the shit out of me, I do wonder about something.
Where are all the psychics? Why have they not zeroed in on her whereabouts? Why no proclamations? Well? Well?
Sylvia Browne? You're suspiciously silent.
All those other dudes who are regularly on tv waffling on about their spiritual guides and so forth. The readers, the white witches, the seers. Why so silent? Why so vague?
Well?
Thought so.
