Legislatures are not perfect. The laws they pass can be vague, overly broad, and can have unintended consequences. Sometimes, the intentions behind laws are lost in interpretation / application by courts. And yes, every now and then, legislatures and courts can be flat-out wrong. Alexander Hamilton, in the Federalist papers, worried about these possibilities, along with the fact that the criminal codes of every nation have, historically, had a natural tendency toward over-severity, harshness.
The obvious solution was to make the executive a meaningful participant in law-making and judicial processes. And the obvious mechanism to assist in this participation was the pardon power - and history convinced Hamilton that there should "easy access" to pardons. The chart below provides some insight as to how the pardon power has, over time, become unidimensional and less frequent.

These data render the conventional wisdom re pardons patently silly. Presidents (and governors) appear to fear the public perception that acts of clemency over-turn the decision making of judges and juries, spring hardened criminal from prison, and toss them into the streets to resume a life of violent crime. The perception is fueled by skews in media reporting and lends itself handily to the notion that 'controversy' and loss of political capital are likely to follow any act of mercy.
In fact, President Obama has pardoned 39 people and there is a better than average chance the reader cannot not name a single one of them. Most committed offenses decades ago and their offenses were so minor they were not even sentenced to prison. The President's pardon simply restored their civil rights. There is not a violent criminal among them, and no political capital was lost by anyone. President Bush granted pardon to 189 people. Can you even name 3 of them? (Scooter Libby was not pardoned, incidentally. His sentence was commuted). Reagan granted almost 400 pardons. This is the REAL face of federal executive clemency, the face that does not make the headlines, the face that - thanks to the media - consistently eludes the American public.
