Lanfranc,
Irish terrorism always sought to minimise casualties and give warnings of bombings.
Also they, like criminals were deterred by the likelyhood of being prosecuted after the event, with unlimited time to investigate, and the benefit of evidence from the scene and their movements to and from the scene.
None of this applies to the new terrorists who expect to die with their victims.
Folkiedave, if the authorities could get away with falsifying evidence, they would not need the new powers.
