Score for privacy rights: In a 4-3 vote, the Supreme Court of Ohio has ruled that police has no right to search your phone without a search warrant, overruling previous lower court decisions on the matter. This is great news.
In the State of Ohio vs Antwaun Smith, the Supreme Court has declared the search of Smith's mobile phone - who was arrested at the time on drug charges - to be unconstitutional, breaking the protection against unreasonable search provided by the Fourth Amendment. The court has decided that mobile phones are "capable of storing a wealth of digitised information" and, as such, they should be considered private. Therefore, police should obtain a search warrant before "entering" into the phone to look for evidence against a subject.
