由于美国宪法第四修正案只适用于国家和公民之间,因此公民私人之间的搜查行为不适用美国宪法第四修正案。由此,私人搜查可能会被政府利用成为政府侵犯公民宪法隐私的有力工具。在研究美国关于私人搜查的司法判例后,我们认为,为限制以上政府的行为、保护公民的隐私,可以采取扩张政府执法人员范围和缩小私人搜查范围的方式。 Because the Fourth Amendment to the U.S. Constitution applies only to states and citizens, searches between citizens and citizens do not apply the Fourth Amendment to the U.S. Constitution. As a result, private searches may be exploited by the government as a powerful tool for governments to infringe the constitutional privacy of their citizens. After studying the judicial precedents on private search in the United States, we think that in order to limit the above government behaviors and protect the privacy of citizens, we can take the approach of expanding the scope of government law enforcement officers and narrowing the scope of private searches.
