On Liberty is the story of today's threats to our freedoms and a highly personal, impassioned plea in defence of fundamental rights, from Shami Chakrabarti, the director of the advocacy group Liberty On 11 September 2001, our world changed. The West's response to 9/11 has morphed into a period of exception. Governments have decided that the rule of law and human rights are often too costly. In On Liberty, Shami Chakrabarti - who joined Liberty, the UK's leading civil rights organisation, on 10 September 2001 - explores why our fundamental rights and freedoms are indispensable. She shows, too, the unprecedented pressures those rights are under today. Drawing on her own work in high-profile campaigns, from privacy laws to anti-terror legislation, Chakrabarti shows the threats to our democratic institutions and why our rights are paramount in upholding democracy.
