American Terrorists

From a brilliant mathematician and an assistant professor at University of California, Theodore Kaczynski became the notorious American criminal—Unabomber—who was responsible for mail bombs that killed three people and injured 23 in eighteen years. He was eventually caught and sentenced to life imprisonment after his anti-technology essay sent to the media was recognised by his brother.

A Gulf War veteran, Timothy McVeigh made headlines after carrying out the Oklahoma City bombing that killed 168 people. He defended his actions saying that he wanted to inspire a revolution against what he considered a tyrannical government. The bombing remains the most malignant act of domestic terrorism in American history. He was executed by lethal injection in 2001.

Eric Rudolph is a terrorist convicted for a series of bombings in the southern US between 1996 and 1998. He is also known as the Olympic Park Bomber. He was listed as one of the FBI's Ten Most Wanted Fugitives for five years before being captured. He is currently incarcerated at the ADX Florence Supermax prison. 

Al-Qaeda terrorist and Islamic preacher Anwar al-Awlaki, initially a university lecturer, had been involved in a number of terrorist attack plots, including one in which they had planned to blow up a Detroit-bound airplane. American-born Yemeni Awlaki died in a drone strike ordered by Barack Obama in 2011.
