It seems to be an accepted part of the populist narrative that every piece of anti terror legislation passed in the past 40 years actually prevented terrorism, so anyone like Jeremy Corbyn, who voted against such measures, was is someway soft on terrorism. This is a complete fiction, legislation like the Prevention of Terrorism Act did little to prevent terrorism but did result in the imprisonment of innocent people, like the Guildford Four and the alienation of communities (first the Irish, more recently Muslims).
Give up your liberties in exchange for security has been the cry of dictators down the ages, the same applies today. Making a bonfire of our liberties does nothing to prevent terrorism, in fact it marks a capitulation to the terrorists who want to destroy our democratic way of life.
