In your opinion, which administration have you known to have issued a pardon that was equally justifiable in the eyes of members of political parties from both sides of the isle?
Any time a President can use their pardon power to free any actually innocent person from a genuinely unjust act, they should do so.
Problem is, we've got Presidents who'd rather abuse it arbitrarily in unjust and fraudulent ways. Thus, "pardon power" probably just shouldn't exist at all I suppose, or at the very least it should have some sort of "guardrails" / oversight attached somehow...
