We spend a lot of money on various secret services to spy on us. Why not turn the intrusion into a service and ask them for files which we accidentally deleted or lost?
But maybe you’re subversive. Like Markus Kompa. In that case, try to get a German passport. Write some document and send a copy to someone whose wires are probably tapped. Now write a letter to an involved secret service and request them to delete the copy (according to German law, you have full control on where, when and under which circumstances one of your works may be published).
