After his computer was stolen, Jose Caceres used a remote access program to log on every day and watch it being used. The laptop was stolen on Sept. 4, when he left it on top of his car while carrying other things into his home. "It was kind of frustrating because he was mostly using it to watch porn," Caceres said. "I couldn't get any information about him." Last week the thief messed up and registered on a web site with his name and address. Jose alerted the police, who arrested a suspect a few hours later. The moral of the story: never go to a porn site where you have to register.
