Newsweek has an investigation into brave people within the Justice Department — Bush appointees — who took quiet but strong issue with the excesses of the Bush Administration in surveillance.  A snippet:

The rebels were not whistle-blowers in the traditional sense. They did not want—indeed avoided—publicity. …They were not downtrodden career civil servants. Rather, they were conservative political appointees who had been friends and close colleagues of some of the true believers they were fighting against. They did not see the struggle in terms of black and white but in shades of gray—as painfully close calls with unavoidable pitfalls. They worried deeply about whether their principles might put Americans at home and abroad at risk. Their story has been obscured behind legalisms and the veil of secrecy over the White House. But it is a quietly dramatic profile in courage.
