Jack Clark and his lawyers, rather than actually try to defend themselves via traditional means available to them in litigation, have decided to make a media circus out of it: he has challenged Pujols to dueling lie detector tests.
One need look no further than the way Clark’s lawyer frames the matter to be tested: he offers that the question to be asked Clark would be whether he was truthful when he said that Pujols’ trainer told him that Pujols had used PEDs.
Yes, Clark’s statements were that Pujols’ trainer told him that Pujols used PEDs.
This is a sideshow mounted in an effort by Clark’s camp to gain some sort of P.R. advantage.
