Also, recently an armed nut went looking for his ex in another county - apparently to do harm, and the nutters local law enforcement called the potential victims local law enforcement to report the problem that was possibly in their jurisdiction. A description of personage and vehicle was given, and the nutters local law enforcement had "pinged" his cell, the ping giving away that the nutter was indeed in the ex's county at that time.
