Feb. 26, 1993 The First WTC bombing occured. 20 years ago today.
The World Trade Center bombing occurred on February 26, 1993, when a truck bomb was detonated below the North Tower of the World Trade Center in New York, NY. The 1,336 lb (606 kg) urea nitrate–hydrogen gas enhanced device was intended to knock the North Tower (Tower One) into the South Tower (Tower Two), bringing both towers down and killing thousands of people. It failed to do so, but did kill six people and injured more than a thousand. The attack was planned by a group of conspirators including Ramzi Yousef, Mahmud Abouhalima, Mohammad Salameh, Nidal A. Ayyad, Abdul Rahman Yasin and Ahmad Ajaj. They received financing from Khaled Sheikh Mohammed, Yousef's uncle. In March 1994, four men were convicted of carrying out the bombing: Abouhalima, Ajaj, Ayyad and Salameh. The charges included conspiracy, explosive destruction of property and interstate transportation of explosives. In November 1997, two more were convicted: Ramzi Yousef, the mastermind behind the bombings, and Eyad Ismoil, who drove the truck carrying the bomb.

because of this and Oklahoma City, trucks and cars cannot get into sophisticated office buildings anymore without being checked.
Laws were changed because of these two events.
20 years later, terrorists have other means, and laws were changed to prevent recurrences of those too.
All that is needed now is to stop the white extremist terrorists who have access or their own legal guns and bullets.
All it will take is either a new court, new people winning elections, and new laws itself.
Back in the early 90s, most Americans were unaware the coming threats.
In 2013 most Americans are aware, and glad of the new laws to stop events like 9-11
and Oklahoma City and the first WTC attack.
