Security quotes of the week

Really? That's interesting. In London the Oyster system is very heavily used by police these days (it's a nice "pay double if you don't want to be tracked this way" system,) but I've never seen much about the London police actually using cellphone tracking much. I suspect that's partly convenience; judging from the numbers of Oyster queries they're doing these days it seems like it's very routine, in a way that might be difficult to manage without close(r) cooperation with mobile operators.
