Imagine a time when a person could exist having never heard of The Beatles. In 1972, when Immigration and Naturalization Services (INS) attempted to deport John Lennon, he hired an immigration attorney that would change the world. Amazingly, his attorney had never heard of him and had no idea that he was about to transform government policy.
To fight the decision to deport Lennon, they not only sought to stop it entirely, but at the very least were trying to delay the proceedings so that Yoko Ono could continue her custody battle (which was taking place in the US), and search for her child, who was abducted by the father (not Lennon). What was achieved went well beyond that, and exposed a secret government program.
