There are dozens of neighbors and relatives that knew the terrorists were potentially terroristic or in training or prep. No phone records needed for that. The feds are shirking their responsibilities to protect Americans while respecting privacy and the tech that makes privacy nearly absolute.
The exception of course is when they actually do their job and gather other evidence on terrorist suspects. In those cases they can demand the passcodes and prevent actual terrorist planning and coordination.
You’re insane. Have you ever done ANY kind of law enforcement investigations?
Unlocking that phone is not worth one more American life.
It is people like you that led to our defeat and humiliation in VN. You had a date yet with Jane Fonda?
