The number of IMSI-catchers (rogue cell towers) has been steadily increasing in use by hackers and governments around the world. Rogue cell towers, which can be as small as your home router, pose a large security risk to anyone with a phone. If in range, your phone will automatically connect to the rogue tower with no indication to you that anything has happened. At that point, your information passes through the rogue tower and can leak sensitive information about you and your device. Currently, there are no easy ways to protect your phone from connecting to a rogue tower (aside from some Android apps which are phone specific and require root access).
This project demonstrates how you can create a rogue cell tower detector using a Raspberry Pi and a SIM 900 module. The detector can identify rogue towers and triangulate their location. The demonstration uses a SIM 900 GSM module to fingerprint each cell tower and determine the signal strength of each tower relative to the detector.

The Plain View Project is a database of public Facebook posts and comments made by current and former police officers from several jurisdictions across the United States.
We present these posts and comments because we believe that they could undermine public trust and confidence in our police. In our view, people who are subject to decisions made by law enforcement may fairly question whether these online statements about race, religion, ethnicity and the acceptability of violent policing—among other topics—inform officers’ on-the-job behaviors and choices.
To be clear, our concern is not whether these posts and comments are protected by the First Amendment. Rather, we believe that because fairness, equal treatment, and integrity are essential to the legitimacy of policing, these posts and comments should be part of a national dialogue about police.
