If by "stand-up guy" you mean "war criminal," he sure is! And how about his focus on marijuana as an evil drug?

McCaffrey and Drugs
Washington D.C. - Leading black intellectuals and public health advocates have joined drug policy reform advocates to criticize Drug Czar Barry McCaffrey for "a series of inaccurate and misleading statements" he has made over the last year. The individuals are sending a letter listing the General's misstatements on February 25, 1999, the same day McCaffrey will testify before the House Committee on Government Oversight. Black Leaders and Public Health Advocates Criticize Misinformation by Drug Czar
The office of drug czar Barry McCaffrey secretly paid the television networks to propagandize its anti-drug message. According to a special report from Salon magazine, the scripts of popular television shows like "ER," "Chicago Hope," "Beverly Hills 90210" and many others were doctored to fit the requirements of McCaffrey's White House Office of National Drug Control Policy (ONDCP). In return for altering scripts, the networks were allowed to sell advertising time that had been promised to the government to other more high paying advertisers.

Barry McCaffrey lies again
DRUG REFORM COORDINATION NETWORK: Our drug czar, retired Army General Barry McCaffrey, appearing on National Public Radio's Talk of the Nation program on Tuesday, July 25th, demonstrated that disinformation is used not only against war time opponents, but also as a debate tactic against a war's domestic critics . . . For example, responding to a caller criticizing foreign anti-drug operations that don't work, instead of spending the money dealing with addiction here at home, McCaffrey said: "Well, you know, we shouldn't argue about facts. They're either facts or not facts. We ought to argue about conclusions. The facts of the matter are, if you look at the US counter-drug budget, it's primarily focused on enhancing prevention, education and treatment." . . . [But] according to the 2000 National Drug Control Strategy, published by McCaffrey's own office, the FY2001 budget includes $12.9 billion on criminal justice and interdiction and source country programs, versus only $6.3 billion on treatment and prevention combined, not at all the "primary focus" of the budget that McCaffrey claimed.
