American former Ph. D. candidate and arsonist

William Jensen Cottrell (born 1980) is a former Ph. D. candidate at the California Institute of Technology who was convicted in April 2005 of conspiracy associated with the destruction of eight sport utility vehicles and a Hummer dealership in the name of the Earth Liberation Front (ELF). He was sentenced to eight years in federal prison on conspiracy charges and ordered to pay $3.5 million in restitution. He was released August 16, 2011.

Cottrell graduated from the University of Chicago in 2002 as a double major in physics and mathematics. He also competed on the school's Division III cross country team, where he was often called the "team genius".

In August 2003, Cottrell and Tyler Johnson developed a plan to place bumper stickers on SUVs reading "SUV = TERRORISM." He was charged with conspiracy to commit arson, arson, and one count of using a destructive device during a crime of violence, in an October 24, 2004 Federal grand jury indictment. Cottrell's lawyers stated that he was diagnosed with Asperger syndrome. At his trial, Cottrell admitted being present, but denied involvement in throwing Molotov cocktails, saying Johnson was the mastermind. An informal network of Cottrell supporters formed, led by the Earth Liberation Front Prisoner's Network and the Free Billy Cottrell organization. These supporters claimed that Cottrell was the innocent victim of government persecution. However, when Cottrell named Johnson as the mastermind, it prompted his Free Billy Cottrell supporters to brand him as a traitor, issue an apology to those who supported Cottrell, and end all support.

An article in the LA Weekly reports that Billy was being mistreated by prison guards who have labeled him a "terrorist". According to the article, he is not permitted to study physics or Mandarin Chinese, is not permitted to teach the other prisoners calculus, and had had his books and papers removed without being given a reason. A letter in Cottrell's defense, signed by Stephen Hawking and other prominent scientists, was distributed to prison authorities and the U. S. 9th Circuit Court of Appeals at Cottrell's October 18, 2006 hearing. Cottrell was then able to study subjects that he was denied at the last prison and no longer had a roommate.

A documentary film on Cottrell, titled Standard Deviation, was written and directed by David Randag and Chris Brannan in 2008. In 2009, it won the Emmy for best student documentary at the Academy of Television Arts & Sciences Foundation's 30th College Television Awards.

On 8 September 2009, Cottrell's convictions and sentences for arson were overturned by the 9th U. S. Circuit Court of Appeals. However, the conspiracy conviction and sentence were affirmed. The omission of Cottrell's diagnosis of Asperger syndrome during his 2004 trial played a key role in the decision. Cottrell was released on August 16, 2011. After his release from prison he completed his Ph. D. in theoretical and mathematical physics at the University of Wisconsin Madison and postdoctorate research at the University of Amsterdam and Stanford University.
