Here's the deal. If the UFO/UAP/whatever things are physical and real, then we're totally screwed. Congresscritters can wail about national security implications but we can't defend ourselves against something that (a) we can't come anywhere near replicating, and (b) breaks our understanding of the laws of physics.

So basically, this is all sideshow. The government can have rotting alien biologic material all they want, it won't tell them anything meaningful. Their best bet would bring in a few hard science-fiction writers. The only thing I agree with is not flooding the media with details of all the unclassifiable stuff they've got.
