"Interceptor use in the US is much higher than people had anticipated.
"One of our customers took a road trip from Florida to North Carolina and he found eight different interceptors on that trip […]."

These tracking devices have existed in the U.S for decades and have even benefited the police and homeland security. However critics suggested that using these devices were morally unethical.
The Wall Street Journal reported in 2011 that the Federal Bureau of Investigations used a [tracking] device known as a stingray to catch tax fraud Daniel David Rigmaiden.
Whilst according to L.A Weekly, The Los Angeles Police Department purchased a stingray/stinger and used it to monitor 21 individuals suspected of murder and burglary. They used this in spite stating the device would be used for 'regional terrorism investigations' in a grant application submitted to the Department of Homeland Security.
Popular Science said that the devices target the smartphone's 'baseband operating system.' This receives radio signals such as Bluetooth and Wi-Fi. Users are worried this compromises the constitutional rights of Americans.
