Bush said that before the Patriot Act went into effect, law enforcement officials had the authority to use so-called "roving wiretaps" – which allow for officials to follow the subject of the court- ordered wiretap from one phone to another – to investigate organized crime and drug dealers but not to investigate terrorists.

On the other hand if we pick up through our intelligence sources that there's some bad actor coming into the United States, we will very quickly alert the FBI to make sure that they get there (inaudible).
