On the night of the arrest—without an arrest warrant—Serge waived his right to call a lawyer. He phoned his wife and told her what had happened and that a bunch of F.B.I. agents were on the way to their home to seize their computers, and to please let them in—though they had no search warrant, either. Then he sat down and politely tried to clear up the F.B.I. agent's confusion.
"He was completely not interested in the content of what I am saying. He just kept saying to me, 'If you tell me everything, I'll talk to the judge, and he'll go easy on you.' It appeared they had a very strong bias from the very beginning. They had goals they wanted to fulfill. The goal was to obtain an immediate confession."
