Track People Using Their Mobile Phones
Richard W.M. Jones writes "A couple of new services have been rolled out in the UK recently which allow you to track people when they have their mobile phones turned on. Mapminder states 'It's important to know where your loved ones are for your own peace of mind'. 192.com asks 'Do you want to know where your children are?'. Of course the police have been able to do this for a long time, and evidence from mobile phone positions has been used in high-profile court cases in the UK. Silicon.com has an article."
if you're going to whack someone, first hide your phone in a restaurant a couple miles away....then you can "prove" you weren't at the crime scene.
Back around 1999 & 2000 there were rumours/news stories about the possibility of being tracked by mobile phones, and much discussion about how it wasn't really technically possible. Phone companies denied it could be done, many law enforcement agencies denied they used it (although some were forthcoming enough to say more). The general consensus was that it was something out of the XFiles.
Now it's commercial a scant 3 years later. Who'd have guessed.

That was about 10 years ago, but certainly shows how cell-phone signal triangulation can save lives.
