Can anyone identify this thing?

I noticed this black vehicle near my house. It has a back plate that say "official" on it. It has police lights inside the top of the windshield. It has a satellite on the roof which is folded down in the picture. If you know what this is for on the roof let me know cuz im kinda curious.

Tahoe jk lmao

It means they're onto you! Jk idk
