Now, it’s true that a serious investigation of Bush-era abuses would make Washington an uncomfortable place, both for those who abused power and those who acted as their enablers or apologists. And these people have a lot of friends. But the price of protecting their comfort would be high: If we whitewash the abuses of the past eight years, we’ll guarantee that they will happen again.

Meanwhile, about Mr. Obama: while it’s probably in his short-term political interests to forgive and forget, next week he’s going to swear to “preserve, protect, and defend the Constitution of the United States.” That’s not a conditional oath to be honored only when it’s convenient.

And to protect and defend the Constitution, a president must do more than obey the Constitution himself; he must hold those who violate the Constitution accountable. So Mr. Obama should reconsider his apparent decision to let the previous administration get away with crime. Consequences aside, that’s not a decision he has the right to make.
