Mass protests have broken out across the United States after a Minneapolis police officer killed black Minnesotan George Floyd while he was in police custody.

One thing demonstrators should be aware of before they head out is that their cellphones may subject them to surveillance tactics by law enforcement. If your cellphone is on and unsecured, not only can your location be tracked, but your messages and the content of your phone may also be retrieved by police either if they take custody of your phone or later by warrant or subpoena.
