Pakistan Tehreek-e-Insaf (PTI) chairman Imran Khan has called on his fellow countrymen and women to read CIA operative Raymond Davis? memoir, which released on June 27, 2017 and has stirred intense debate across Pakistan and worldwide.

Taking to Twitter on Saturday, Imran said, ?This book should be read by Pakistanis to understand why we are treated with so little respect internationally.?

?The book is a shameful account of how our top political & military leadership collaborated to let a cold blooded killer, responsible for 4 deaths, go scot-free,? the PTI chief added.

Raymond Davis ? the CIA operative who sparked a diplomatic row after gunning down two men on the streets of Lahore in January 2011 ? has penned his side of the story for the first time in a memoir titled 'The Contractor: How I Landed in a Pakistani Prison and Ignited a Diplomatic Crisis'.

According to Davis, John Kerry, Nawaz Sharif, Asif Zardari, former ISI chief Gen Ahmed Shuja Pasha and Husain Haqqani helped in his release from the Kot Lakhpat Jail.

Raymond Davis releases memoir on 2011 killings, diplomatic row in Pakistan

The CIA operative tells his side of the story for the first time since he sparked a diplomatic crisis by gunning down two men in Lahore in January 2011

Apart from the ISI chief, several other officials of the intelligence agency were present in the court at the time of his release, he notes in the book.

The violent episode escalated into a diplomatic crisis, making front-page headlines across the world and straining ties between Islamabad and Washington, as US policymakers pressed for diplomatic immunity for Davis and pushed for his immediate release.

According to an Amazon.com introduction, the book offers "an up-close and personal look at the 2011 incident in Lahore, Pakistan, that led to his imprisonment and the events that took place as diplomats on both sides of the bargaining table scrambled to get him out".
