Hi Jay The source that you ve used the strategy written by McCaffrey is okay but it would be very good if you would also mention some third party source that discusses or describes the strategy In the lingo of Wikipedia I think the strategy itself is called a primary source but Wikipedia generally prefers secondary sources I can look for secondary sources for this if you d like Also perhaps a bit more concise For example I don t think it s really significant that McCaffrey recognized that illegal drugs remain widely available which is common knowledge Cheers
