" While the Texas prison officials remained in the dark about what was going on, they were fortunate that William and Danny had benign motives. Imagine what havoc the two might have caused; it would have been child's play for these guys to develop a scheme for obtaining money or property from unsuspecting victims. The Internet had become their university and playground. Learning how to run scams against individuals or break in to corporate sites would have been a cinch; teenagers and preteens learn these methods every day from the hacker sites and elsewhere on the Web. And as prisoners, Danny and William had all the time in the world.

Maybe there's a lesson here: Two convicted murderers, but that didn't mean they were scum, rotten to the core. They were cheaters who hacked their way onto the Internet illegally, but that didn't mean they were willing to victimize innocent people or naively insecure companies. "
