Does warrantless GPS tracking back again?

Hi guys! One friend of mine told me that his car was tracked by GPS tracking device and it was OK according to his local court. Still they have violated the Supreme Court ruling that prohibits such tracking, aren’t they? Can we stop that someday and somehow?

Due to the spread of smartphones using, also caused a lot of civilization problem in public places, including the above teenagers use a mobile phone to play games, they will open up to the voice of the game is great , to the next person kind of noise pollution. Moreover, in some quiet places, they call loudly, causing others to rest and read. There are many things like that, almost all of which happen to teenagers. Some people who have been poisoned by these things have called for banning the use of mobile phones by students, or for the use of cell phone jammers in quiet public places.

For example, the last case I heard about was in Iowa where some guy named Angel Amaya was accused in drug trafficking and few of his cars were warrantlessly tracked by GPS tracking devices in Iowa and 6 other states. It was the case of so called “good faith” when the suspect is tracked relying on the binding precedent in the Court of Appeals of any US Circuit.

Similar GPS tracking cases were also presented at 7th, 8th and 9th Circuit Courts and they have ruled that warrantless GPS tracking during the cases was legal. Those circuits cover such states as Illinois, Wisconsin, Iowa, Minnesota, Indiana, Arkansas, Missouri, Nebraska, Alaska, Arizona, North and South Dakota, California, Guam, Mariana Islands, Montana, Hawaii, Idaho, Oregon, Washington and Nevada.
