I might be slightly off with Carbyne directly connecting to NYPD, but I swear it was in the wikipedia entry last week. Anyhow here's some indirect connections for you.

The Founders Fund has invested in hundreds of startups and has been an early backer of some of the most significant companies of the past decade, including SpaceX, Palantir, Facebook, and Airbnb.

If you go digging Palantir is or was in a legal dispute with the NYPD.

A guy from Palantir recently went to work for Carbyne.

Note also https://en.wikipedia.org/wiki/Ehud_Barak is all over the news due to his connections to Jeffrey Epstein as well. Being he is connected to both Palantir and Carbyne.

That would be the recently altered wikipedia entry for Carbyne.

As of last week, that entry mentioned Carbyne covering Cities in Mexico, And NYC and I think it said San Francisco. The wikipedia entry has been changed now and mentions next to nothing.

You're welcome to go digging for yourself.
