Sotomayor said the case "presented a very complicated question" because there had been two cases addressing how much information a warrant had to contain in order for the police to search a defendant's computer. "I was looking at it in the backdrop of the conflict that it appeared to contain in our case law, and what our case law said was important for a police officer to share with a judge," she said. "I held that the acts violated the Constitution, but that the evidence could still be used, because the officers had -- there was in law a good-faith exception to the error in the warrant."
