One item that caught my eye was spending on the DEA of only $3.14: Wikipedia puts yearly spending on law enforcement related to the War On Drugs at about $44 billion [1] and gross federal tax revenue for 2009 at about $2.1 trillion [2]. This works out to roughly 2% of tax revenue spent on the War On Drugs. For the $5,400 of federal income tax in the linked example that would work out to more like $100 rather than $3, no?
Of course, the Wikipedia article doesn't state how much of the $44 billion goes to the DEA and how much goes to other law enforcement agencies.
