Taylor v. Nevada

Issue: (1) Whether the warrantless access and use of hundreds of data points showing the petitioner's historical cell phone location over a weeklong period was a search that violated the petitioner's federal Fourth Amendment rights; and (2) whether the show-up of the petitioner was unnecessarily suggestive, resulting in unreliable out-of-court and in-court identifications that violated his federal constitutional right to due process of law.
