CSS is used by the Department of Homeland Security (DHS) law enforcement component to provide real-time cellular device location for research purposes. This allows law enforcement to identify both the subject of investigation and the victim.
In the cases investigated by the OIG, a search warrant was obtained for the use of CSS. However, Watchdog notes that the Secret Service and ICE HSI do not always obtain the court orders required by CSS policy and federal law when using CSS during investigations involving dire situations. said.
The OIG says there are two reasons for this. First, the CSS Policy does not contain sufficiently detailed guidance on working with external law enforcement agencies. Second, the Secret Service and ICE HSI did not correctly interpret the CSS policy, which reflects the statutory requirement to obtain a court order before using CSS.
