Attacks on U.S. chemical facilities have the potential to affect thousands, possibly millions of people, yet many of them remain poorly secured. Legislation to improve security standards has been watered down.
A recent avian flu outbreak in the United States has forced agriculture officials to destroy tens of millions of birds and has cost hundreds of millions of dollars. These are the public health and food safety concerns.
Lee H. Hamilton, the vice-chairman of the National Commission on Terrorist Attacks upon the United States (also known as the 9/11 Commission), says "I would agree with the general assessment that we are safer than we were prior to 9/11, but we are not safe." While he is concerned about better protecting the United States from weapons of mass destruction, he is greatly worried about bioterrorism and ordinary chemical weapons.
