Planning on going to a protest? You might not be aware that just by showing up, you can open yourself up to certain privacy risks — police often spy on protesters, and the smartphones they carry, and no matter how peaceful the demonstration, there’s always a chance that you could get detained or arrested, and your devices could get searched. Watch this video for tips on how to prepare your phone before you go to a protest, how to safely communicate with your friends and document the event, and what to do if you get detained or arrested.

This is the first in a new series of videos I’m hosting called Cybersecurity for the People. In future videos we’ll dive into topics such as encrypted messaging apps, password management, and how to become a whistleblower. If you have topics that you’d like to see covered in this series, please let me know. You can email me at micah.lee@theintercept.com or send me a Signal message at 415-964-1601.
