US facing attacks by home-grown terrorists, senior adviser warns - Telegraph: "The sheer volume of terror plots against the US means that the country will become unable to prevent a fatal terror attack by a new breed of extremists radicalised in America's towns and cities, the top counter-terrorism official has warned."

In unusually candid remarks, Michael Leiter, director of the National Counterterrorism Centre, said that the nation's defences would be probably be breached by a home-grown radical, after a year-long period containing several failed or thwarted attacks that had seen the most intense terror activity since September 11, 2001.

"Although we aim for perfection, perfection will not be achieved. Just like any other endeavour, we will not stop all the attacks," he said.

"If there is an attack, it may well be tragic. Innocent lives will be lost. But we still have to be honest, and we have to be honest that some things will get through."
