Twenty years after the 9/11 terrorist attack that claimed almost 3,000 lives (and still counting), will there be justice?

The nation somberly continues to observe the 20th anniversary of three separate but coordinated terrorist attacks, allegedly by Islamic terrorists using airplanes as weapons, on the morning of Tuesday, Sept. 11, 2001.

The attacks claimed nearly 3,000 lives (including 400 police officers and firefighters), and left untold numbers of others with long-lasting medical and psychological injuries that to this day continue to add to the carnage.

Meanwhile, more is being uncovered about the attacks on 9/11 -- on the World Trade Center in New York City; the Pentagon building in Washington, D.C.; and a plane crash near Shanksville, Penn.

The investigation into 9/11, said to be the single largest foreign attack on American soil, continues. At its conclusion, it is expected that a series of formal actions will be taken by the United States and demands made of governments said to have sponsored the attacks.
