Earlier this month, we wondered what was going on with the dual investigations into the Paterson administration. One probe, you may recall, centers on allegations that Paterson and the State Police tried to silence a woman who accused Paterson's top aide of beating her; the other scandal has to do with the same aide, David Johnson, soliciting free Yankees World Series tickets for the boss. Well, today the Times reports that Johnson has been called to testify twice, but has kept his mouth shut, invoking his Fifth Amendment right not to incriminate himself. Neither the state attorney general’s office nor Johnson's attorney will comment, but on the lawyer's law blog, he calls the Fifth Amendment the "safe harbor of the innocent" and "not the refuge of the guilty."
