Re Hunter's and anybody else's text messages, not only does the NSA, other intel agencies, and FVEY+ partners have them all, so too does the wireless carrier(s) on both ends, the device OS company on both ends, and the hardware manufacturor on both ends.
Consider the vastness of knowing regarding criminal activity, pedo and murder imagery and evidence, and location data that all these companoes have and do nothing good with.
Apple/mac OS/iphone
Alphabet/google/android OS
Nokia, samsung, etc
Verizon, att, sprint, tmobile, etc
They all know and always have.
