In 15 minutes it gets underway: Attorney General Eric Holder’s first big round of testimony to the Senate Judiciary Committee since the right began raising doubts about trying Khalid Shaikh Mohammed and the other 9/11 conspirators in civilian courts. Holder will probably want the hearing to focus on other Justice-related subjects, but it’s likely to become a showdown on the merits of the Justice Department’s place in a counterterrorism strategy, something the attorney general has vigorously defended. What will he say about civilian courts’ capabilities for trying terrorists? What will he say about the military commission alternative that the Obama administration has embraced as well? It’s all coming up momentarily.
