True enough, you can only kill a guy once. With all the various expenses that the court system sticks the public with...this is a blessing in disguise. The guy is toast...it may be 3 years before he is executed...but he is finished. Lets just be happy that he screwed up and got caught in the region that he did. Had this been California....he would be on a life sentence only. And that would be terribly wrong.
Had this been California, he'd be back out on the streets by now searching for the "real sniper."
