“If the police come knocking at your door, the constitution offers you some protection. But the constitution is just a piece of paper—if you don’t know how to assert your rights. And even if you do assert your rights…what happens next? That answer may seem complicated, but protecting yourself is simple if you know your rights. That’s why EFF has launched an updated Know Your Rights Guide that explains your legal rights when law enforcement try to search the data stored on your computer, cell phone or other electronic device. The guide clarifies when the police can search devices, describes what to do if police do (or don’t) have a warrant, and explains what happens if the police can’t get into a device because of encryption or other security measures.”
