However, during the course of the investigation someone told the media that the plates were stolen and they blew through the toll booth. The fact that the media put this stuff on the air doesn't make the investigators wrong for subsequently reporting the facts correctly.
It does make a case for not jumping to conclusions based on media reports. A case can also be made that if the subsequent facts fail to support your original conclusion, it might be time to reconsider your position.
You didn't read my post very well. It was an LE spokesmen at a press briefing who said that the plates didn't match. It was also widely reported at the end of this whole thing that they were cited for running through the toll booth. Strange action if they didn't actually do it.
