I've got four questions: 1- what system was used to geo-tag those pictures? GLOSNAS or GPS? 2- Who controls the GPS and is able to shift coordinates locally?

I've got four questions: 1- what system was used to geo-tag those pictures? GLOSNAS or GPS? 2- Who controls the GPS and is able to shift coordinates locally? 3- Who owns Instagram (ie. who is able to order them doing things, and order them not saying anything about being ordered)? 4- Where are the servers where those pictures are stored (who controls them)? Those pictures are absolutely no proof, since the coordinates can be manipulated both before or after the picture is taken. You can perhaps use geotagging to bully and make fun of poor chaps in your high school class, but it's no argument for a WWIII.
