You're really on to something with parallel construction. Using Palantir they can map all the celltower data, etc, to find people who are present at the place and time of multiple crimes. But they don't want to explain all this in court. So they sit Constable Collins down with the video footage to parallel reconstruct evidence for the jury. And the PR department then decides to turn him into a super-hero with mythical powers, to further the cover. That makes a lot more sense to me.
