Problem with your analysis, damned if you do, damned if you do not. Many of the activities of the three letter US agencies have become largely criminal with gross and purposeful misinterpretations of the law and this not in pursuit of justice but in the pursuit of the psychopathic ego of many out of control 'agents' or upon the direct orders of political or corporate appointees. So doing nothing is no more or less effective at getting you door kicked in, being threatened with real and impending death for any reason imaginable including not obeying orders fast enough, a barking dog, happening to have some item in your hand at the time, any item. Then you and all other people in residence at the time being physically assaulted, really assaulted, not grab you hands put them behind your back and being handcuffed but thrown to the ground kicked and jumped on, a bought of "stop resisting' with more blows to the head and then of course your home trashed and your stuff stolen. Then if they hate you ludicrous bail conditions the ensure you remain in jail for years during an hugely purposefully extended trial and the inevitably had sucker you have been in jail for years, plead guilty and you will released with time server ha ha ha.
Basically you are attempting to defend yourself against really lazy and self serving types who in reality wont be bothered with the real leg work, the real reports or any real effort.
Besides it can be hugely fun. Be overtly covert, make a big show of analogue person to person communications. Don't be lazy yourself, do everything you can person to person, the more the merrier and the more wasted spy vs spy efforts. In the whole spy vs spy vs the rest of us, being overt, exposing your efforts, being more public about your activities, serves to protect you and will inevitably expose their spy vs spy efforts to the ridicule and derision it so often rightly deserves.
