What 2014 US Supreme Court case disallowed automatic evidentiary downloading from a cell phone via Search Incident to Arrest?

The case of Riley v. California is pivotal in the realm of digital privacy rights and law enforcement procedures. In this landmark decision, the Supreme Court ruled that police cannot automatically search a cell phone without a warrant when making an arrest. The court recognized that cell phones hold a vast amount of personal information and are fundamentally different from other physical objects that may be searched under the "search incident to arrest" exception.

The decision underscored the need for law enforcement to obtain a warrant to access digital data on cell phones to protect individuals' privacy rights. This ruling reflects the understanding that digital information stored on devices like cell phones warrants greater protection from government intrusion due to the sensitive and private nature of the data they contain. Consequently, this case established a crucial precedent for how digital evidence must be treated in the context of searches incident to arrest.
