In Praise of Chinese Walls

Colby Cosh makes a compelling point about the congressional intelligence report on the Sept. 11 massacre.

Congress appears rueful that a "wall" was built in the 1960s and 1970s between domestic policing of the American republic and the gathering of foreign intelligence, because it prevented the relevant agencies from coordinating their data and making the connections (INS-CIA-FBI-NSA) that might have saved the World Trade Center. Well, the people who built that "wall" were perfectly aware that it would have the effect of decreasing the efficiency with which the citizenry was protected. They built it because the power to protect is also the power to detect, persecute, and destroy. The wall serves to prevent a police state being created in America. That's important: not lip-service important, but future-of-the-human-species important. If getting rid of Saddam Hussein was worth American lives, the continued existence of the wall unarguably is.
