The FBI and the Department of Homeland Security (search) are warning that terrorists may try to use helicopters and limousines as weapons, according to newly-released bulletins sent to law enforcement agencies throughout the country.

The warnings, which include concerns about a range of rental vehicles that could conceal powerful bombs as well as storage facilities, were issued Friday night and were obtained by FOX News.

The bulletins urge extra vigilance by people who operate car and truck rental businesses and those who handle airport security. The FBI repeated the government's concern that Al Qaeda intends to attack the United States in the next few months, prior to the Nov. 2 election.

The FBI and DHS said that Al Qaeda remains committed to using aircraft for future attacks within the United States.

Al Qaeda exposed: Are we stopping or stalling them?

A sample of your responses:

I think we are simply stalling the terrorist. 
They have all the time in the world to carry out their plans.

Thank-God for President Bush, and the fact that we are swatting them like flies. If Kerry was in charge, Saddam would still be in power, along with the inspectors. We'd still be listening to Hans Blix.

We have not stopped Al Qaeda. They have the patience of Job. They know that the more we try to secure our county they can find a hole in it. They just wait in the wings and bide their time. It's not a question of when, it's the question of where.

I would say that we are BOTH stopping and stalling them. I feel confident that our intelligence and protection agencies are doing an excellent job of deterring and undermining terrorist plans for the United States.
Unfortunately we can truly only claim to stall them since no matter how many plans, and attempts, we break apart we will only find that the terrorists will be moving right along and starting a NEW plan for either a similar and same target. Until the entire mindset of the terrorist is crushed (not placated mind you, but annihilated) we can never honestly claim to have stopped them.
I am very proud of the people we have protecting us, because even when they had a catastrophic failure, they quickly got back in the saddle and adapted to get back up to speed and get back on task! It's too bad it's become all too much of a favorite pastime in this great country to continually kick our hard working, and very successful, intelligence services.
