From Liberty’s press release:
Shami Chakrabarti is to be the new Director of Liberty. She succeeds John Wadham who has been appointed Deputy Chairman of the Independent Police Complaints Commission.
…
Shami Chakrabarti joined Liberty in 2001 as the group’s ‘In-House Counsel’ and is now recognised as one of the UK’s leading authorities on anti-terror laws. She says that the measures adopted by the Government in the aftermath of the September 11 attacks have made her “ashamed to be a lawyer.”

So that’s what it takes to make someone ashamed of being a lawyer. Every day’s a schoolday.
