This is just one more reason not to carry a phone, let alone one that's turned on all the time.
I can't take the battery out of mine so its pretty much always on.... at least, that's the only safe assumption.
ever increasing punishments
Evidently you're not in the UK. Tough on crime, tough on the victims of crime.
Sorry, but I have no sympathy if an armed robber is caught and convicted and then jailed for 30 years. Good. Thankfully I've never had a firearm pointed in my face by an angry stranger, but I can only imagine its terrifying and deeply traumatic. What I wonder is how the hell their defence was considered before the courts when it essentially amounts to "Well, yes, my client did do the armed robbery but Officer Wiggam may have been lax on his paper work so my client shouldn't be punished". In a reasonable system Officer Wiggam may also face sanction but that shouldn't absolve the scrote of their played for and got justice.
For those of a criminal bent, having the phones location tracked may be problematic, but for the honest citizen it can also be useful. I can prove that I wasn't speeding through Wales in a car with my cloned number plate on it last week because my phone records show me as visiting family in Edinburgh at the time and they're backed up by witness statements.
I'd prefer not to be tracked all the time, obviously, but I've never worried that so being would fit me up for a crime I didn't commit. Does anyone here really worry about that? If so please can you explain why in rational terms?
