Police investigators now routinely ask criminal suspects to turn over their cellular phones or I-pads during interrogation sessions. These devices often can disclose a wealth of information about the suspect and his activities, associates, etc.
The radio waves emanating from cellular phone transmission towers are not subject to Fourth Amendment constitutional protection against unreasonable searches and seizures as land lines are; the U.S. government has set up receivers that are capable of intercepting these radio waves in order to monitor such phone communications.
Back in the 1970s, when less than one per cent of the U.S. population had mobile phone communication devices, I was able to pick up such communications on a police band/short wave radio receiver I purchased from Radio Shack that could pick up the same frequencies as the telecommunication companies at that time were using.
Today many police agencies have close relationships with telecommunications providers for assistance in obtaining information helpful in targeting criminal suspects or other "persons of interest".
