Despite warnings from the nation's top intelligence officials that a domestic terrorist attack is likely within the next six months, Los Angeles faces no greater threat than it has since the Sept. 11 attacks, a top police official said Wednesday.

Deputy Chief Mike Downing, who heads the anti-terrorist division in the Los Angeles Police Department, said none of the information provided to the U.S. Senate Intelligence Committee on Tuesday broke new ground.

"We have seen activity in other parts of the world that have transnational reach," Downing said. "We have always been concerned about it. We know about the training camps in Milwaukee and the whole use of the Internet to reach people."

Officials representing the CIA, FBI and other intelligence agencies told the committee that they expect another terrorist attack on the United States in coming months.

In particular, the officials said they are concerned with the use of the Internet and cyber-security issues.

"What keeps me awake at night is that al-Qaida and its terrorist allies and affiliates could very well attack the United States," CIA Director Leon Panetta told the congressional committee.

Downing, who has a force of 300 officers and works with the federal government in a joint intelligence center, said his group is concerned not only with al-Qaida, but also with what experts call the "inside-outside" threat - when someone inside the country carries out an attack on behalf of outside interests - along with the "lone wolf" terrorists.

"One of the areas of most concern is the homegrown terrorist," Downing said. "They are inspired by the al-Qaida idealogy and act on that."

One of Downing's duties is to communicate with the local Islamic community, where he said he is welcomed.

"The city of Los Angeles may have its problems, but the majority of the Islamic community is not one of them. Our engagement has been very positive, and we have a lot of partners in the Islamic community who believe in our country and democracy. They believe the killing of innocent civilians is not part of Islamic beliefs."

At the same time, Downing said, officials are aware of a Pew Institute study that shows 4 percent of Muslims have a favorable view of al-Qaida and 1 percent have a very favorable view.

"If that is correct, that means there is a population of 125,000 people in the country with that view," Downing said.

For the average citizen, Downing advises people to be alert to potential danger and contact the LAPD for assistance.
