For those wondering if a president can pardon someone who hasn't been convicted of anything, according to the Supreme Court, yes.<p>From Ex parte Garland, 1866:<p>> The power thus conferred is unlimited, with the exception stated. It extends to every offence known to the law, and may be exercised at any time after its commission, either before legal proceedings are taken, or during their pendency, or after conviction and judgment. This power of the President is not subject to legislative control. Congress can neither limit the effect of his pardon, nor exclude from its exercise any class of offenders. The benign prerogative of mercy reposed in him cannot be fettered by any legislative restrictions.<p><a href="http://caselaw.findlaw.com/us-supreme-court/71/333.html" rel="nofollow">http://caselaw.findlaw.com/us-supreme-court/71/333.html</a>
