tivoli here to discuss the policies. i'm not able to get into my personal view as far as how i feel about that. the department of justice itself -- we have to follow the regulations -- is treating the content of e-mail communications as requiring a warrant issued by the court. >> that is common sense. what is the argument that an e- mail is different than a letter? the government coming in and reading people's mail? .> it is a point of view content older than 180 days, that was very specific. law is concerned, it is not treating it differently except for content that is older than 180 days. that is being looked at differently right now under present law. that is why folks are seeking to make adjustments. now under present law and policy, anything that is 100 days or older is treated the same way as a written communication in a letter. >> i just want to clarify for the average listener. it is our understanding that subpoenas are used for e-mails that are older than 180 days. the justice department has not implemented a ne

that iran could not divert safeguarded materials and produce a weapons worth of uranium before the tivoliis discovered. can you tell us about how much warning you believe we would have quick. >> clearly we continue to hold the most likelyssessment, our assessment is that if they were anm which d a dead giveaway it wouldn't be produced other than for a weapon most likely scenario is the would do that covertly. to actually slow the time or lengthen the time to which they could develop a testable single weapon. clearly, if they were to do a breakout using the facilities they have now to enrich uranium which is as you indicated under safeguard and under iaea supervision that clearly is a real bellwether. that would be a big warning. if they were to do thatch i think is the least likely scenario, it would be a fairly brief time as we indicated in a statement. >> a fairly brief time? >> well there are imponderables they are on how an industrial process you are involved in, so there are all kinds of factors that can affect that time but we are talking about it period of months, not years. >> hav
