LONDON -- The British government's measured and firm response to the attacks in London on July 7 has had the support of all political parties. The resolution of the general public to get on with their life has not wilted.

There is, of course, universal sympathy for the innocent victims of this outrage and backing for the police and the security services in their efforts to trace the criminals responsible. This will be a very difficult task and Londoners must be on their guard against possible further attacks.

It is important that any new measures to deal with the threat should be measured and proportionate. Britain must not allow the terrorists to undermine its basic freedoms; if it were to do so it would be conceding victory to them. Britons may have to accept more restrictions, but these should be subject to proper judicial oversight, proper review and only renewed if deemed necessary by a consensus.
