The arrests made in Toronto and the recent news out of London should serve as a stark reminder that al Qaeda and related groups are not sleeping-they are actively pursuing the tools of terror and plotting against our people and our cities. Law enforcement must have every legal tool at their disposal for the surveillance, tracking and capture of al Qaeda and other terrorists.

And though some oppose the NSA's terrorist surveillance programs, it is clear that our law enforcement and intelligence forces need the right tools, the right focus and the right people to 'connect the dots' and prevent further attacks from al Qaeda. And they need to be able to do this while the terrorists are planning attacks and purchasing bombs-not after they've set them off.
