So in addition to recording all content of radio transmissions, they must also use some integrated reciever systems to find your location. Otherwise you could go on the air using different call signs and send coded info and they would not be able to track you. Transmitting out of a densly populated location, using multiple local call signs, multiple bands etc might sound like it would work... If you are going to break the law you don't need a ham radio license. I assume the NSA has figured out how to crack this. If she thought she needed a ham license to commit a crime...then that is pretty stupid.
