Reuters is reporting about a Brazilian, traveling in Germany, whose home security system (in Brazil) sent him a text message that his home had been broken into.
Sr Wettlauser logged onto his home webcam, saw the thief was still in the house; he then called his wife (in Sao Paulo), who called the police, who arrested the thief.
My point? Just that a novel use of otherwise innocuous technologies may lead to questions about traditional ideas on surveillance and policing. I doubt many of us would have connected text messaging and home security.
