Sleepwalking to 42 day detention

[AboveTheSalt]

A 'mass sleepwalk' will take place through the streets of Leeds tonight as Amnesty International attempts to wake people up to the erosion of civil liberties as shown by the UK Government's plans to extend detention without charge to 42 days (Link).

In response to the obvious question Why Leeds?

Amnesty International said it had chosen Leeds to launch its campaign because it was targeting MPs who voted for a 42-day limit in June, but who voted against Tony Blair's earlier plan for a 90-day limit. (Link)

Based on past experience, it may also be that Amnesty International were unable to get permission for a protest in Central London?
