Is it possible for the states they traveled through to revoke their drivers licenses? I mean they've presented ample evidence that they've intentionally exceeded speed limits on average over the entire route.
I think they can also be brought up on criminal charges in most states they passed through. Their radar detectors and, especially, their jammers are strictly illegal in many, if not most states in the US and yet they just gave the authorities pictures of their illegal setup with their names and faces and testimony that they used said illegal setup to enact willful and flagrant violations of the law. I really do hope the authorities come knocking holding a warrant with this article as the justification for issuing it.
It looks like radar detectors are legal in most US states and territories. Virginia and the District of Columbia are the two exceptions and the NYC->LA route wouldn't pass through either.
