Cell site simulator device; require law enforcement agencies to obtain warrant before using.

Mississippi's SB 2331 requires law enforcement agencies to obtain a court-issued warrant before using cell site simulators (devices that mimic cell towers to track phones or collect data). The bill allows warrantless use only if officers determine an immediate threat to life or safety from terrorism, with strict time limits (24 hours) and data deletion rules. It prohibits collecting or keeping data from non-target devices, requiring such information to be deleted within 48 hours. This law directly affects all Mississippi state and local law enforcement agencies using these tracking devices.
