The prosecution and the defence have presented their final arguments for and against Tahawwur Rana's culpability in 26/11 Mumbai attacks. Prosecution pleaded for justice to the Mumbai attack victims and the defence portrayed the Pakistani-Canadian Rana as a man duped by conman David Headley.A federal jury hearing the case is now set to begin its final deliberations to decide Rana's fate after the closing arguments were presented in the court that is set to deliver the verdict.Rana himself, however, chose to remain silent and did not testify at his trial that stretched for a fortnight.The 50-year-old doctor is charged with providing material support to terrorists by providing cover for main accused Headley while he laid the groundwork for the Mumbai attack in which 166 people died in a two-day siege.The government prosecutors argued that there was overwhelming evidence of not only Rana having the knowledge of but also assisting and providing material support to his childhood friend Headley in carrying out the attack in November 2008.They pleaded for justice for the victims of the ghastly terror attack in India.US attorney Daniel Collins said to the 12-member jury in his final arguments in a packed court room that those who died in Mumbai demand justice and Rana knew that his trained terrorist friend Headley was bent on killing people.Collins said what happened in Mumbai could have happened in Copenhagen. 164 people died in flurry of bullets in Mumbai.Such horrific acts take place with help of a number of people.Meanwhile, Tahawwur Rana has told FBI that ISI has been giving weapons to terrorists before they enter Kashmir. This was revealed in a video of Rana's questioning by the FBI, played for the first time during his trial at the court in Chicago.
