I am guessing the people who brought him up on charges have never actually read a science textbook. Sure its a little winded and takes a while to get to it, but by reading the average science textbook from jr high and above you can figure out how to create some pretty dangerous chemical reactions that should scale fairly well. Knowing about something and being jailed for it it thought crime. Trying to set limits on the human condition of curiosity and interest could pave the path of a dangerous road.
