The popular school of thought and the one seemingly supported here opposes torture and asserts that torture is pointless because it doesn't work, but past experience shows that that is not necessarily correct torture has worked in the past. Even if we (UK or whoever) do not torture our Intelligence and Security Services cannot refuse information so obtained which could/would protect our own people. The terrorist chooses to kill and maim and can also choose not to suffer in captivity, while denying any choice to his or her victims.
