Richmond County Daily Journal: StingRay is why the 4th Amendment was written by Olivia Donaldson:
Imagine you are in the middle of your typical day-to-day activities. Maybe you are driving, spending time with family, or working. If you are like most people, your phone is at your side on a daily basis. Little do you know that, at any time, police and law enforcement could be looking at information stored on your phone. You haven’t done anything wrong. You haven’t been asked for permission. You aren’t suspected of any crime.
Police have the power to collect your location along with the numbers of your incoming and outgoing calls and intercept the content of call and text communication. They can do all of this without you ever knowing about it.
