On March 12th, at around 2:30 a.m. in two towns in Texas (the DeSoto and Lancaster areas) hackers took control of the emergency
The alarms repeatedly went on and off until 4:00 a.m., when authorities regained their control.
The areas interested by the incident were hit by tornadoes several times in the past, for this reason, the authorities build an emergency tornado alarm system.

The police are investigating the intrusion in the alarm systems of the two towns, the authorities will be intransigent with those who have breached into a critical system on which human lives may depend,
