NEWS: WASHINGTON -- It's been just one month since Timothy McVeigh was executed for the Oklahoma City bombing, and U.S. officials are trying to prevent similar disasters. At a government summit on Wednesday, Attorney General John Ashcroft said that thwarting terrorist attacks was his "number-one priority" and that the Feds were stepping up efforts to guard against chemical, biological, radiological and nuclear threats. Ashcroft said the Justice Department was already planning for 2003 an exercise called "TOPOFF2" -- which stands for "top officials" -- involving simulated attacks carried out with no notice against American cities. The first TOPOFF took place in May 2000 with a mock biological attack on Denver and a fake nuclear bomb near Washington, D.C. The attorney general also predicted noose-tight security during the 2002 Winter Olympics, which will be held in Salt Lake City. "We are doing everything we can to ensure that people from all over the world can come to the Games, bring their families, enjoy the excitement of world-class athletic competition, and feel safe and secure," Ashcroft said. During the 1996 Summer Olympics in Atlanta, federal agents falsely accused security guard Richard Jewell of being responsible for planting a small bomb that killed two people. ANY THOUGHTS?
