Newswise — “Janet Napolitano is certainly correct that the risk of home-grown terrorism has never been more severe. Responding to this inevitable conclusion presents unique challenges for our country, especially since the American ethos is infused with an unparalleled commitment to freedom of expression, association and religion.

“Some U.S. citizens worry that the executive branch has entrenched its power through the use of warrantless wiretaps, surveillance of religious groups with allegedly extremist tendencies, and undercover operations that could be vulnerable to entrapment defenses in court.

“The best response to this concern is to reaffirm our national commitment to robust judicial oversight of these programs in accordance with our constitutional structure.”
