Michael Drebeen, a deputy solicitor general in the Obama administration, had a rough morning last Tuesday. He argued two Supreme Court cases back to back, defending a notoriously vague federal criminal statute -- and the justices worked him over vigorously. The 1988 law at issue aims at public corruption and corporate misconduct, but sweeps far too broadly, criminalizing schemes to "deprive another of the intangible right of honest services." If that language seems a little, well, intangible to you, you're not alone.
