writes "An appellate court has finally supplied an answer to an open question left dangling by the Supreme Court in 2012: Do law enforcement agencies need a probable-cause warrant to affix a GPS tracker to a target’s vehicle?
The justices said the government’s statement “wags the dog rather vigorously,” noting that the primary reason for a search cannot be to generate evidence for law enforcement purposes. They also noted that “Generally speaking, a warrantless search is not rendered reasonable merely because probable cause existed that would have justified the issuance of a warrant.”
The justices also rejected the government’s argument that obtaining a warrant would impede the ability of law enforcement to investigate crimes."Link to Original Source
