Signs of the Times: (1) A 24-year-old Muslim woman was strangled in Newcastle, Australia, in April when the bottom of her burqa became tangled in the wheels as she was driving playfully at a go-cart track. (2) A 45-year-old, out-of-town man was killed in a street robbery in Oakland, Calif., in July after he became distracted while typing a location into his cell phone's map program to find his way to a job interview. The appointment was at Google Inc. (3) Horatio Toure, 31, was arrested in San Francisco in July after snatching an iPhone from a woman on the street and bicycling away. Unknown to him, the woman was conducting a real-time demonstration of global positioning software, and thus Toure's exact movement was registering on her company's computers. He was arrested within minutes.
