Light 'em up!
Pretty hard for the public to see inside the back of a package car. Other then the big rear door.
As long as the picture is obviously taken from the outside. If it was clearly taken from the inside of the package car, don't be surprised if disciplinary action is taken. Personally, I would not want to put myself in this situation. Have known of a few cases of termination for taking pictures. They got their jobs back, but one of the drivers lost over a weeks pay.
