>However, the FBI can send a remote message to ANY phone to turn on its microphone and essentially use it as a wiretap. That's been built into every phone in the USA for something like 10 years now. It's why you have to surrender a cell phone in secure locations and military bases.
Really? When a phone is off, it's off, I don't believe the FBI can make a phone that has been hard powered off come up and start recording. The hardware just isn't capable of doing anything when it's hard powered off (evidenced by the fact that most phones need a signal to establish what time it is when you power them on.)
So how many cell phones do you know that a powered off with a hard switch. You know, flip the switch like you do on your living room light. Or how many people do you know that take their battery out when the power their phone off. Well there is your answer.
Again, how do you know the phone is powered off unless you have a flip switch connected to the battery, take the battery out (and at the same time assume there is other smaller battery in there) ?
