I'm trying to remember, but wasn't the San Bernardino peaceful shooter's phone inspected by the FBI to see who else was in on the massacre?
They requested the backdoor/keys to unlock it from some tech giant.
Apple or Microsoft told the FBI to pound sand.
Something.... something... about "privacy"... it was just too important to protect the dead jihadist from prying eyes.
Innocent people who happened to go to DC in January?
"Oh, no problem FBI, we're here to help you with personal information, can we close their accounts, too?"
All true. They wouldn’t help prosecute an actual terrorist, but they’ll happily hand over personal information about peaceful patriotic protesters.
