mr. saresne, critics site to the fact the sec has not sought to service a subpoena in the five years since the circuit's decision. you have heard criticisms today. they say it's not really a problem that needs to be solved because of that fact. is this true and if so, why hasn't your agency sought to challenge the policy adopted by many providers following warshack? >> the decision was made at the the time -- i wasn't at the sec at the time. but it was made in excess of caution not to issue subpoenas to isp's without consent of the subscriber. since i've been there we have held off on doing that in difference to the discussions. at the same time we have never felt like warshack precluded us from obtaining e-mail under the constitution pursuant to a subpoena with notice to the subscribe subscriber. it dealt with no notice to a subscriber. where a subscriber or the party you're seeking e-mail from or material from has precompliance review before a court that that satisfies the fourth amendment. we have not done it but there are cases ongoing. >> i know you haven't done it. i want to know why
