I can't give you an endtime. We're hoping to get in there within the next hour. That's about the only time-- because we have no idea how long any of this is going to take, so I can't put an endtime to it because, of course, I emphasize again the importance of public safety. It's safe right now, with the evacuations; we don't need to rush anything and we're going to do our best and take our time to just keep it as safe as possible."<br/> <br />Authorities have evacuated the area and have brought in scores law enforcement and explosives experts.<br/> <br />Deborah Lutterbeck, Reuters
