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.
