On the page about the letter to/from Kaczynski:

"His 35,000-word manifesto on the evils of industrialized society, which he forced newspapers to publish on the threat of more violence, was remarkably free of spelling and grammatical mistakes."

This makes no sense. Kaczynski was a professor of mathematics; I'd hardly call a professor that can write correctly "remarkable". What's remarkable is that the article author would write something so stupid.
