The Los Angeles Sheriff’s Department is in the third day of an outage of its computer-aided dispatch system in its vehicles, leaving deputies to resort to old methods as they respond to calls.

It’s not clear how long it will take to fix the problem, but in the meantime deputies and dispatchers must use radios instead of patrol car computers.

LOS ANGELES (AP) — The archaic computer dispatch system for the nation's largest sheriff's department remained out of commission on Thursday after crashing on New Year's Eve, forcing deputies to handle all calls by radio, authorities said.

The LASD said its computer-aided dispatch program — known as the CAD — was “not allowing personnel to log on with the new year, making the CAD inoperable.”
