After the lecture the audience questions drifted on to civil liberties.

On the subject of the detention of suspects without charge Straw said: "They may not have a 28 day detention system in France but you can keep some witnesses for up to a year. They would rather our system."
He put the falling crime rate down to better use of CCTV and spoke about the retention of DNA records for legal purposes.
"I would be perfectly happy to hand my DNA sample over. Some judges think that it's not a bad idea to have a universal database and that may be a better way of doing it. I agree."
Straw said: "I wholly refute the idea that this is a government that erodes liberty," highlighting the work the current labour government has done on race relations, human rights and freedom of information. "We have got no plans to repeal the freedom of information act," he added.
Straw also highlighted the international nature of his role. "I have to deal with two million Brits living in Europe and five million living abroad. A quarter of the people living in London were not born in the UK. We are a extraordinarily heterogeneous society."
What do you think?
How long should criminal suspects be allowed to be detained without charge? Should public institutions be obliged to release information to members of the public on request? What rights should the government have to withhold information requested? How should the threat of terrorism be dealt with?
