On careful rereading, this sounds highly suspicious. Apparently the driver didn't back up the woman's story, so he's been charged also. This makes it 5 to 1 on the story. Not at all impossible that the 5 are lying, although I would think that the driver would have little reason to lie to protect the sailors.
He may change his story for a plea bargain, and the charges against him may be part of the pressure being put on him.
What sailors?
