And this is why I think Palantir is behind PRISM

Palantir makes multiple products.

What their rep said is they sell a product that happens to be called Prism, and that product is used for banking.

Do a bit of reading and you'd also discover some high-ups in Palantir got there after attempting to develop a similar system in-house with US government intelligence agencies. IIRC, it's not known whether those programs were successful.

Did you actually just try to prove that Palantir has military/intelligence contracts to prove their involvement with NSA's PRISM?

And why is the CIA an investor?
