Even from his cell in a maximum security prison in Florence, Colorado, Theodore Kaczynski, better known as the Unabomber, remains a thorn in the side of the authorities.
The New York Times today carries a fascinating article about the latest twist in a three-year legal battle over what to do with Kaczynski's papers and other possessions from his remote mountain cabin.
Turned in by his brother David after one of the FBI's longest and most expensive manhunts in 1996, Kaczynski is embroiled in a legal battle over a government plan for an auction of sanitised versions of his writings on the internet so proceeds can go to four of his victims.
A federal judge in Sacramento approved the idea as a way for the group seeking restitution to collect some of the $15m (£7.6m) it is owed by court order.
However, the judge ordered that any references to Kaczynski's victims in the documents be deleted.
In the latest development, Kaczynski has claimed the changes would violate his right to freedom of expression and has mounted a legal challenge, raising the possibility he will appear in court to represent himself unless he is provided with a new lawyer who is an expert in the first amendment on free speech.
In addition to Kaczynski's writings, items to be auctioned include more than 250 books from his cabin. Among them are The Brothers Karamazov, Roman Political Ideas and Practices and Fundamentals of Analytical Chemistry.
Then there are bowstrings and arrows in a quiver, two axes, a scabbard and a Montana driver's licence.
David Gelernter, a Yale professor who was badly hurt by one of Kaczynski's bombs, recently sent an email to the New York Times, in which he said he had nothing but pity and contempt for anyone who would bid on Kaczynski's items unless "they're acting for a police agency or some serious research project that seeks to rid the world of (not 'understand') such vicious cowardly thugs".
