Not only that, but there's no indication that use of Palantir would have been illegal in any way in the case, only that if analysis leading to the conviction was obtained with Palantir, then it was withheld from the defendant. Conversely, they argue, if Palantir held no such analytical evidence, then its absence is proof of innocence. That later part if very much a stretch though, as it implies a level of sophistication, if not omniscience, that is not in reality possible.
