It was in St. Paul last week that Palin drew raucous cheers when she delivered this put-down of Obama: "Al-Qaeda terrorists still plot to inflict catastrophic harm on America and he's worried that someone won't read them their rights."

But Obama, who taught constitutional law at the University of Chicago for more than a decade, said captured suspects deserve to file writs of habeus corpus.

Calling it "the foundation of Anglo-American law," he said the principle "says very simply: If the government grabs you, then you have the right to at least ask, 'Why was I grabbed?' And say, 'Maybe you've got the wrong person.'"

"The reason that you have this principle is not to be soft on terrorism. It's because that's who we are. That's what we're protecting."

Palin's quip was troubling; I'm pleased to see Obama call her on it, but I don't expect her to seriously engage the subject. It was a throwaway line for her.

Here are two threads on the subject from earlier this year:

Benjamin Wittes’ Law and the Long War is required reading for anyone interested in the legal challenges posed by the war on terror.

Six years after the September 11 attacks, America is losing a crucial front in the ongoing war on terror. It is losing not to Al Qaeda but to its own failure to construct a set of laws that will protect the American people—its military and executive branch, as well as its citizens—in the midst of a conflict unlike any it has faced in the past.
