I am not so sure! Mercy is a powerful reason to act but some matters have so many political overtones and could send the wrong message, that, as I say, I am not sure. Pollard is not a man to be admired. He committed treason against his country for monetary gain; he has since suggested he did it for the love of Israel, but that doesn't sell very well, although it gains him support from the Israeli right. How about freeing Marwan Barghouti? What he did certainly was not for money, certainly did not involve any personal action on his part, and more surely than Pollard, was done for love of his country, or at least the country he believed should be recognized for his people. As I say, pardons are tricky. And grant the one if the other was granted as well.
