According to his Facebook page, his sentence has been commuted, which means that he still has this conviction, but his conviction is being appealed. If New Jersey's appellate courts overturn the conviction, the judge who sentenced Aiken will get pimp-slapped AND all of New Jersey will have slightly more sane gun laws. A pardon doesn't help to correct the underlying flaws of a bad judge and a bad law.
Of course, if his conviction is upheld, Christie can pardon him.
