How did Headley become an international terrorist timeline

The deposition of David Coleman Headley began before a special Mumbai court on Monday where he is expected to reveal the sequence of events and planning behind the 26/11 terror attacks. It is for the first time in the Indian legal history that a foreign terrorist is providing his evidences through video link.

Here is how Headley became an 'international' terrorist from being a nondescript:-

February 8, 2016: Headley deposes before a special Mumbai court from an undisclosed location in the United States through video conference on between 7 am to 12.30 pm. The deposition is being recorded via video conferencing.

December 10, 2016: Headley was pardoned and made an approver by Additional Sessions Judge G.A. Sanap who presides over special cases related to terrorism, including those under the now repealed TADA.

The court had told Headley that he "disclose full and true facts leading to the happening of the attacks within his knowledge and the persons concerned, disclose his role and the role of others, disclose facts which he has admitted before the U.S. court in Illinois and truthfully and correctly answer the prosecution's questions unfolding the entire criminal conspiracy and other offences."

Accepting his role in the attacks, Headley said, "I pleaded guilty in the past to the charges in the US and I admitted I was a participant in these charges... I appear here ready to answer questions regarding these events, if I receive a pardon from this court."

January 24, 2013: US District Judge Harry Leinenweber of the United States District Court for the Northern District of Illinois in Chicago sentenced him to 35 years in prison for a dozen federal terrorism crimes relating to his role in planning the November 2008 terrorist attacks in Mumbai, and a subsequent proposed attack on a newspaper office in Denmark.

According to Headley's guilty plea and testimony, he attended the following training camps operated by Lashkar: a three-week course starting in February 2002 that provided indoctrination on the merits of waging jihad; a three-week course starting in August 2002 that provided training in the use of weapons and grenades; a three-month course starting in April 2003 that taught close combat tactics, the use of weapons and grenades, and survival skills; a three-week course starting in August 2003 that taught counter-surveillance skills; and a three-month course starting in December 2003 that provided combat and tactical training.

December 2011: The National Investigation Agency had filed a charge-sheet accusing Headley, his Pakistani-Canadian accomplice Tahawwur Rana, Lashkar founder Hafiz Saeed and seven others of conspiracy. The charge carries death penalty.

October 3, 2009: Arrested by the FBI at O'Hare International Airport in Chicago while on his way to Pakistan.

March 2009: After the Mumbai attack, Headley made a sixth trip to India to conduct additional surveillance, including of the National Defense College in Delhi, and of Chabad Houses in several cities.

September 2006- July 2008: Headley made five extended trips to Mumbai each time making videotapes of various potential targets, including those attacked in November 2008. Before each trip, Lashkar members and associates instructed Headley regarding specific locations where he was to conduct surveillance. After each trip, Headley traveled to Pakistan to meet with Lashkar members and associates, report on the results of his surveillance, and provide the surveillance videos.

Before the April 2008 surveillance trip, Headley and co-conspirators in Pakistan discussed potential landing sites in Mumbai for a team of attackers who would arrive by sea. Headley returned to Mumbai with a global positioning system device and took boat trips around the Mumbai harbor and entered various locations into the device.

February, 2006: After receiving instructions in late 2005 to conduct surveillance in India, Headley changed his given name from Daood Gilani in Philadelphia to facilitate his activities on behalf of Lashkar by portraying himself in India as an American who was neither Muslim nor Pakistani.

November 26-28, 2008: 10 attackers trained by Lashkar carried out multiple assaults with firearms, grenades and improvised explosive devices against multiple targets in Mumbai, including the Taj Mahal and Oberoi hotels, the Leopold Cafe, the Chabad House and the Chhatrapati Shivaji Terminus train station, each of which Headley had scouted in advance, killing approximately 164 victims and wounding hundreds more.
