If you have been in jail or prison, or know someone who has, you know how important phone calls are. When you are locked up the phone is your lifeline, your connection to loved ones, family, and your attorney. What many people do not know is that, in Minnesota at least, you do not have any privacy rights during jail phone calls; jail staff can record the calls and the prosecution can listen to them. Some prosecutors are big on listening into calls from people they are prosecuting. While the law does prevent them from listening to calls with attorneys and we hope they follow that law, there are no limits on them listening to calls with anyone else.
The moral of the story is do not say anything on the jail phone that you do not want the prosecutor to hear.
