Millions of people spend their day chatting away on their cellphones, ordering groceries from Amazon�s Alexa, making calendar appointments with Apple�s Siri, or posting on Facebook about the last concert they attended. Sharing our personal information via social media platforms or providing it to third party companies has become so common place in our routines that it begs the question, �What, if anything, in our personal lives is really private?� As we grow more comfortable using modern technology to streamline and stay connected, are we risking our right to a reasonable expectation of privacy, a protection garnered by the Fourth Amendment of the U.S. Constitution? Modern innovation has presented the judiciary with unique challenges, as the court balances the legitimate interests of government and the people. We will explore the dynamics of Carpenter v. United States, United States v. Miller, and Smith v. Maryland, and the recent developments surrounding the Golden State Killer and the Arkansas murder case involving Amazon�s Alexa.
