U.S. President George W. Bush pledged on Wednesday to boost protection of U.S. transit systems against an attack in the aftermath of the London bombings and urged Congress to renew provisions of a post-Sept. 11 anti-terrorism law. At least 56 people were killed in the bombings of underground trains and a bus at the height of morning rush hour in London on July 7. "It should be a vivid reminder about the world in which we live, we will not let down our guard," Bush said during a visit to the Port of Baltimore, according to Reuters. "The best way to protect the homeland is to go on the offense, is to find these people in foreign lands and bring them to justice before they come here to hurt us," Bush said. "We're working with people around the world. We're on the hunt and we will stay on the hunt," he said. About a dozen provisions in the USA Patriot Act, which was enacted in response to the Sept. 11, 2001, attacks, are set to expire at the end of this year unless renewed by Congress.
