5. John Lennon
The case of John Lennon was simply a matter of someone being too popular for the elite to fathom. Most of those in power did not appreciate the following that he had gathered over time. Such were his tribulations that the INS had already made attempts to have him deported. Apart from the INS, the FBI ran constant surveillance on him.
For Lennon, his biggest mistake was speaking out against the evils that had taken root in the industry. According to conspiracy theorists, his assassin had been under mind control by the Illuminati when he proceeded to kill John Lennon.
