I have seen the future, and it is monitored
Today, if I wanted to perform surveillance against a target, I would tap his phone line. In the very old days I would physically attach to phone lines, but these days I work with the telephone company to obtain electronic access. The telcom is a service provider and as such is subject to CALEA, which mandates providing various snooping capabilities for LEA use.
