to turn to vienna. you heard about this attack by frernly advisers or at least people who are friendly to america warning of an attack there. is it a legitimate warning? and how concerned should folks be about this? it s a legitimate warning but it s not clear just how authentic the details are behind it. it s a warning that came from a friendly intelligence service. the austrian police are taking it seriously. wee not sure if the names they ve handed out mount up to possible attackers. as we can see from events in paris and subsequent events in europe, it s a time of greater vigilance than normal. as to whether or not there will actually be an attack, that s one of those things that it s difficult to say. daveed, thank you very much. the latest police shooting
