San Francisco Chronicle:

A federal judge declared California's death penalty unconstitutional Wednesday, saying delays of 25 years or more in deciding appeals and carrying out occasional executions have created an arbitrary and irrational system that serves no legitimate purpose.
This is actually one argument against the death penalty I haven't heard before (the others usually revolve around the ethics and utility of killing as state-sanctioned punishment, racial bias, and instances of exoneration subsequent to executions).

But it sure is snappy. Read the full ruling by Judge Cormac Carney here.
