We plan to spread the long version among our prison physicians as a sort of manual. Thanks for your immeasurable efforts."

Our psychologists and psychiatrists would not say your pamphlet contributed to the fact that much but we both knew it did, didn't we!" Ladislav Valent, Ministry of Justice, Czech Republic.
