I just read this story on NBC news where this snippet was included at the end of the article:
Arrington applied for a pardon nine years ago. He said the prosecutor in charge of his case and the sentencing judge were among dozens who wrote letters on his behalf.
If the prosecutor is going to write a letter on your behalf to get you pardoned for the crime they helped convict you for, why in the hell didn't they just drop the damn charges in the first place?! I mean, it's good that they went to help the guy out now, but it would have been a whole lot better for the guy, not to mention efficient for our judicial system, to not have put him through all of that to begin with.
