Hi Jay  The source that youve used the strategy written by McCaffrey is okay but it would be very good if you would also mention some thirdparty 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 youd like  Also perhaps a bit more concise  For example I dont think its really significant that McCaffrey recognized that illegal drugs remain widely available which is common knowledge  Cheers
