"...people with histories of domestic violence have managed to trick telecommunications companies into providing real-time location data by simply impersonating US officials over the phone..."
For those who may be in danger of such things, you may want to consider a location mocking app. Although, TBH I'm not sure if that would defeat E911 which the carriers use.
@0x56 I am fascinated. But if you are a domestic abuse survivor your phone is your lifeline. If you somehow alter it how are they going to find you when you do need 911? In rural areas it won't work anyway but theoretically?
@Klaatu_Veratta_Nectarine - a very good point... I know my location mocking app can easily be switched off, but I'm not sure if I'd remember to do so in an actual emergency.
