If the elected Congress is able to rat out these alleged secret programs and brings them back under the standard Congressional oversight, then at least you have the possibility of some information being made public.
I don’t know about you, but if there is indeed a non-human intelligence occasionally visiting Earth, I would like to know, even if details about e.g. their technology aren’t made public.
And if all there is to it is some high-ranking officials making stories up and lying to Congress, I also would want them to be put behind bars for wasting the time of our elected representatives.
