While this amendment protects the right to privacy from the government, it also brings forth exceptions: reasonable search and seizure as well as infringements allowed by court-issued warrants seeking specific items or people. Other amendments used to extend privacy by the Supreme Court, namely the First, Third, Fifth, Ninth, and Fourteenth, do not have notable exceptions regarding privacy. Limitations of Reasonability Defining what constitutes a reasonable search has proven to be difficult. In Katz v. United States ([[Probable year:: 1967]]) the Supreme Court ruled the Fourth Amendment protects “people, not places” and created the Katz test to determine where it is reasonable to expect privacy from law enforcement and a warrant is needed (Katz v. United States, [[Probable year:: 1967]]) . This test examines whether the information was meant to be kept private and if it had been disclosed (Hu, [[Probable year:: 2018]], 129). Prior to the Katz test, the court used the trespass test, a common-law approach to the Fourth Amendment in which physical intrusion can violate the Fourth Amendment. Fifty years after Katz, the Court again relied on the trespass test in United States v. Jones (Hu, [[Probable year:: 2018]], 130; United States v. Jones, [[Probable year:: 2012]]) . In doing so, the court claimed while the Katz test extended the right to privacy to people, it did not revoke the traditional common-law protections (United States v. Jones, [[Probable year:: 2012]]) . Hu, citing Justices Sotomayor and Alito, feels that the Katz test ends before cyber-surveillance begins and recognizes the need for change (Hu, [[Probable year:: 2018]], 139, 141). In analyzing Fourth Amendment Supreme Court rulings, Orin Kerr found that four general models have been used to decide privacy cases ([[Probable year:: 2017]], 524). These models vary in scale (micro or macro) and normativity (normative or descriptive) and consider one of the following: how public the information is, what information was found, the actions that were taken, or whether or not government conduct should be regulated (Kerr, [[Probable year:: 2017]], 506, 524). Kerr claims the last of these considerations was the basis for the Katz ruling ([[Probable year:: 2017]], 519). Unfortunately, the Supreme Court has used all four of these models to both protect and deny privacy and has not provided clear guidance as to what is a reasonable search (Ker, [[Probable year:: 2017]], 507, 508). Kerr concludes by suggesting there is no one size fits all test or model because of the importance of case facts ([[Probable year:: 2017]], 525). As such, Kerr would rather see many definitive models so that the limitations of reasonability are clear and contextualized for future court decisions at all levels ([[Probable year:: 2017]], 542). Privacy Violations by a Non-Government Entity The Supreme Court has rarely ruled on notable cases in which the privacy offender was not a government entity. However, in Senn v. Tile Layers Protective Union ([[Probable year:: 1937]]) the Court ruled that Senn could not invoke his privacy in work against the right to publicity of the union’s picketing (Richards, [[Probable year:: 1334]]) . In the opinion of the Court, Justice Brandeis held that because it was a commercial dispute and affected the competition for customers, the right to privacy was not applicable (Richards, [[Probable year:: 1334]]) . He also protected counter-speech in this opinion (Richards, [[Probable year:: 1334]]) . References Hu, M. ([[Probable year:: 2018]]) . Cybersurveillance intrusions and an evolving Katz privacy test.
