The bomb goes off. 75000 people are dead with another 200000 suffering from various degrees of damage to their lungs. There are reports of vigilante mobs across Great Britain attacking minorities, not just muslims, but anyone who does not look European. The overworked police force and army struggle to contain the violence. The casualty figures among the victims of mob violence are in the hundreds, with thousands of foreign owned small businesses burnt to the ground. In order to contain the violence government declares martial law...

This is Britain you're talking about. They would not declare martial law, they would politely offer you a choice between behave and Scotland.
