... Pollard was set up and took the rap for Aldrich Ames's betrayal ..Um, sure, this was the verdict the jury returned: we find the defendant--or, rather, we find that the defendant needs to be found guilty in lieu of someone else.
The government agreed to a plea bargain which the judge ignored because the CIA via Capar Weinberger gave the judge a brief falsely claiming that Pollard had done irreparable damage.
To this day the CIA has refused to give this brief to Pollard's attorneys. Making it public would expose the coverup that someone in the CIA (Ames and his controller?) used to deflect suspicion against themselves. Even when Ames was found to be the one who betrayed the US agents you and your ilk continue to blame Pollard and thru him Israel for giving the info to the Soviets.
Now the CIA is covering up the coverup to avoid even more egg on its face hence Tenent's opposition to Pollards clemency.
