@blatham,
He is not just making denials now, but he alleges a conspiracy amongst his accusers. It is like saying in court, "I am not guilty, what's more, the prosecuting witnesses have conspired with each other to make accusations against me." In court, that would be his/her defense, but that defense would have to have background and a basis for the accusation. They couldn't just throw it out there for the jury to chew on.
