Again, you folks act like RF energy cannot be controlled, it just goes off in all directions no matter what you do and that there is no way to isolate the jamming energy to small areas. This is not true. Would there be some residual affect outside the intended area? Perhaps, but if you do this right it would not be wide spread, nor would it need to extend more than a few hundred feet beyond the desired areas....
Tell me it's not possible to limit where you put the RF and control the signal strength outside the desired area to acceptable levels... I think you can do that, if you are careful and think about where you put the jammers, what antennas you use and what direction you point them.
Also, GPS jammers are neither expensive nor rare. They are off the shelf and have been for decades and well with the budget of the Secret Service (In fact I'd bet they ALREADY have a few). Directional antennas are also inexpensive and off the shelf, even at the frequencies of GPS. None of this is rocket science... Just a bit of engineering.
