LUD
From Wikipedia, the free encyclopedia
LUD (Local Usage Details) is a detailed record of local calls made and received from a particular phone number. These records are regularly available to police in the United States with a court order, and were traditionally subject to the same restrictions as telephone tapping.
The term is frequently heard on the TV shows Law & Order and The Wire. Example: "We need to pull his LUDs before we can expect concrete proof of his involvement."
