From The New York Times:

This Congress is replete with oversight investigations — the murder of American officials in Libya, the misdeeds of the Internal Revenue Service — that have produced lots of headlines and little substantive change. When it comes to the most pressing matter — homeland security and the threat of terrorist strikes — there are plenty of congressional eyeballs, by one count 119 panels. This generates more chaos and confusion. With duplication and petty turf fights, Republicans and Democrats alike have put parochial politics ahead of security.
