There is some truth in that. If the Tory party was totally at ease with the issues of liberty and rights and did not fear being boxed into a corner by another terrorist attack, there would be no need for Davis to resign his seat. With Labour’s dreadful showing in the polls, the Tories may be tempted to sit on their hands and simply watch the beleaguered Brown without making any big analysis.
A small scale terrorist attack (say 10-20 deaths) on London could give Brown short term relief from Labour’s hard times and give the government even more of a platform for reducing civil liberties. Cynical, but true.
