Absolutely and that's probably the average case. Now take the hundreds of thousands of other people that have run into issues, and take the 0.1% most extreme cases. This makes up essentially 100% of what you read in the media. For instance this case actually started when Canada refused entry to her for fear she was attempting to work illegally.

To say it's an unusual case is an understatement, but all you will read about in the media is unusual cases.
