celebs of this stature rarely make their own travel arrangements. I think it's more likely a huge error on the part of an assistant who didn't properly research the rules before arranging the trip details. It a false document was presented, it was likely produced by an assistant. I'd be surprised if Mr. Depp and Ms Heard intentionally thumbed their noses at the law. It's more likely it was an honest mistake, and when they were made aware of the mistake, they took the dogs home again. No harm, no foul. I'm sure it's not the first time it's happened ... just the first time it's happened to an A-list actor, which makes for great headlines.
