Sufficient evidence for conspiracy.
In case of alleged judicial bribery, referring to the injustice of the underlying proceeding in opening and closing statements of the bribery trial would not be sufficiently plain error to justify reversal.
Even if evidence was more prejudical than probative, harmless error, given the weight of the evidence.
As co-conspirator would have been subject to a wide variety of challenges on cross-examination, court's granting of 5th amendment privilege as to questions that did not directly jeopardize the co-deft was not a violation of the Sixth Amendment right to compulsory process.
Any sentencing errors harmless. No cumulative error.
