最高法院统治周五，如果他们希望通过收集他们使用他们的手机的信息，在数字时代借给他们在数字时代的隐私利益的地方来跟踪犯罪嫌疑人的动作，警方普遍需要搜索权证。
The justices’ 5-4 decision marks a big change in how police may obtain cellphone tower records, an important tool in criminal investigations.
首席大法官John Roberts由法院的四个自由主义者加入，说手机位置信息“详细，封存，毫不费力地编制。”Roberts写道，“一个人在他的身体运动记录中保持了对隐私的合法期望”，因为他们被手机塔捕获。
罗伯茨表示，法院的决定仅限于手机跟踪信息，并不会影响其他商业记录，包括银行持有的物品。
他还写道，警方仍然可以回应紧急情况，并在没有逮捕令的情况下获取记录。
正义Anthony Kennedy，Samuel Alito，Clarence Thomas和Neil Gorsuch每次都写了异议意见。肯尼迪写道，法院的“新和未知的课程将禁止执法”，并“保留被告并审判猜测多年来”。
The court ruled in the case of Timothy Carpenter, who was sentenced to 116 years in prison for his role in a string of robberies of Radio Shack and T-Mobile stores in Michigan and Ohio. Cell tower records that investigators got without a warrant bolstered the case against Carpenter.
调查人员通过法院命令获得了Cell Tower记录，该法院命令需要较低标准的标准，而不是获得逮捕令的“可能的原因”。“可能的原因”需要有力的证据表明一个人犯下了罪行。
The judge at Carpenter’s trial refused to suppress the records, finding no warrant was needed, and a federal appeals court agreed. The Trump administration said the lower court decisions should be upheld.
美国公民自由联盟,代表Carpenter, said a warrant would provide protection against unjustified government snooping.
The administration relied in part on a 1979 Supreme Court decision that treated phone records differently than the conversation in a phone call, for which a warrant generally is required.
“政府的立场未能争夺数字技术的地震变化，这使得不仅可以跟踪Carpenter的位置，而且还有其他人，而不是短期，但多年来几年，”Roberts写道。
The earlier case involved a single home telephone and the court said then that people had no expectation of privacy in the records of calls made and kept by the phone company.
“政府的立场未能争夺数字技术的地震变化，这使得不仅可以跟踪Carpenter的位置，而且还有其他人，而不是短期，但多年来几年，”Roberts写道。
The court decided the 1979 case before the digital age, and even the law on which prosecutors relied to obtain an order for Carpenter’s records dates from 1986, when few people had cellphones.
The Supreme Court in recent years has acknowledged technology’s effects on privacy. In 2014, the court held unanimously that police must generally get a warrant to search the cellphones of people they arrest. Other items people carry with them may be looked at without a warrant, after an arrest.
