More and more often, phones are a source of evidence in criminal cases. This is simply because many people use their smartphones exclusively to communicate. They send text messages, direct messages, social media messages and email messages. They can transfer data files, pictures, videos and much more. This would have taken a wide variety of devices in the past, but now people can do it all on their smartphones.
As a result, the police often want to get the information from the phone when looking for evidence that someone has committed a crime. Maybe they think you have engaged in a conspiracy with other people and the messages between group members are on the phone. Or maybe the police believe you’ve been selling illegal drugs and you are taking orders through social media. Are they allowed to search your phone for evidence?
They probably need a warrant
They can, but they often need a search warrant in order to do it. This is similar to how the police can’t search your house without a warrant or your consent, for instance. If you don’t give them consent to open the phone, they can’t force you to do it without getting a search warrant first.
That said, you may not be the only target for that warrant. Think about how you sent those messages and what apps you used. Maybe you were using Facebook Messenger to communicate. In theory, the police may be able to get the data logs from Facebook by serving Meta with a warrant, meaning they don’t actually need to access your phone at all. The information they’re looking for is already stored in the cloud, so they can get it from other sources, without your involvement.
Technology makes modern criminal cases highly complicated. If you’re facing charges, you must know about all of your defense options.
