The whole war on terror and this bulk collection is predicated on stopping crimes before they happen. It's a giant catch 22.
Would stopping mass shootings and not-called-terorrism-but-domestic-terror be part of the use cases here? Like if you were to ignore some other laws and track gun ownership and purchases, maybe cross reference it with the use/prescription of certain medications and then cross reference that with anti-social posts on the internet or associations with certain call-themselve-patriots-but-really-hate-the-government type groups you might stop some mass shootings. Maybe save some actual lives.
It's a terrible rabbit hole to go down, we need to stop it all ASAP.
The best thing about this whole setup is that it's unfalsifiable. Something bad happen? We need to work harder (read: accept more invasion of our privacy) to prevent such atrocities in future. Nothing bad happens? It's working, let's do it even more!
