One way is if in a bad situation with crimes and cops are being told something bad is going to happen because of some call or text, they can go in and see who the person is and search through the phone records. This act can keep us humans safe in the long run because of the proof being showed. This can help with murders and their records from the phone, drug dealers by catching them sell or where those specific spots are, gangs, and many more things. I feel this is more efficient in bigger cities because crime and bad stuff happens in those areas. This helps with catching the bad people put on this world, and to know what to watch out for when strange people make calls and text
