2 Operations of the Reich BNSF/Stasi

In the dark early morning with no sound but a few birds, BNSF from across town single taps the horn when I reach the backdoor. No trains, no freight is moving. Yet the town is a railhead. What is seen here is a standard rather than a coincidence as shown in this collection of videos. It can only be executed with satellite surveillance inside the home. Used domestically apparently by the U.S. military franchised to local law enforcement - and all the more heinous with public access.
