Creepy idea, that the FBI might be spying on school kid’s phones, but well, maybe it’s not an all bad idea.
If a government run public school gives you a phone, you probably have to sign some tiny line giving your consent to being ‘wiretapped’ for lack of a more modern phrase at the convenience of the government.
The article perpetuates a misconception. The software in question does not spy on the activity on a phone, but it can download the activity on a phone that is in the possession of the investigator. However, the phone usually has to be unlocked for the contents to be accessible.
