I can't see any way in which a "Pardon Power" can ever result in anything except miscarriage of justice. If you think there needs to be an escape hatch to fix injustices then you have a bigger problem.
I can. Let’s say for example that the Computer Fraud and Abuse Act was used to prosecute you for downloading JSTOR documents which you had already access to. And you are facing the cumulative maximum penalty of $1 million in fines, 35 years in prison, personal asset forfeiture. Now, would a pardon from the highest executive office be a miscarriage when the prosecution should never have happened in the first place? I…
If you assume, hypothetically, that the justice system is operating as it should, a pardon means giving one person the right to ignore the laws of the country for a select few acquaintances.
If one has to tolerate this blatant avenue for favoritism, I’d rather see the Supreme Court or judges themselves invested with this power, rather than the president.
I guess I am biased by believing in the separation of the executive and judiciary powers.
