The current bout of global terrorism came to the heart of London today in a fatal attack outside the Palace of Westminster. The symbolism is impossible to escape. An assault on the home of democracy induces a peculiar sense of outrage. That people, including a policeman, should die in such an assault is tragic.As yet, nothing is known of the motive. All that can be said is that the attacker failed to enter parliament itself. Bystanders were killed and injured, but the massive security inevitable for such an institution was effective in protecting its occupants. In a busy modern city there is no way absolute security can be assured, but the police can say that the system was tested and worked. Short of holding parliament in a bunker, there are limits to what more can or should sensibly be done.
The Westminster attack is a tragedy, but it’s not a threat to democracy
