FISA hearings and processes are very secretive and unconstitutional. We've become accustomed to intelligence agencies blatantly violating our rights but it's okay because it might stop criminals.
The state claims state secrets and prevents jurisdiction/standing when these laws are challenged. It doesn’t work.
There is a large body of history about these unconstitutional laws at this point. It would be wise of anyone willing to make such claims to orient themselves with the current status quo and how we arrived here.
This assumes an infallible judicial system which ours is NOT. I find the blind trust in the courts a very boring and unhelpful take. What do you personally think about FISA, Patriot Act, etc.. which makes it easy for the government to spy on its own citizens?
The rot runs deep.
