An anonymous reader writes "Bad news: a Canadian who visited New York had his laptop stolen. Good news: it was outfitted with Prey, the open-source computer tracking application. Better news: a group in NYC made a 'geek squad intervention,' faced the culprit and retrieved the laptop safely. This case naturally raises the usual sorts of questions about the 'Twitter posse' culture." The victim-turned-victor is author and consultant Sean Power.

British teenager Luke Angel has been banned from the US for sending an email to the White House calling President Obama an obscenity. The 17-year-old says he was drunk when he sent the mail and doesn't understand what the big deal is. "I don't remember exactly what I wrote as I was drunk. But I think I called Barack Obama a p***k. It was silly -- the sort of thing you do when you're a teenager and have had a few," he said. The FBI contacted local police who in turn confronted Luke and let him know that the US Department of Homeland Security didn't think his email was funny. "The police came and took my picture and told me I was banned from America forever. I don't really care but my parents aren't very happy," Angel said.
