Saying they would "die on their sword" is wrong. Nobody would care if they said "we're waiting 6 months because we want time to debate". They do that sort of thing all the time, doesn't raise a blip. This is a fringe issue! Nobody understands or cares about cybersecurity, that is the only reason that they can get something like this passed.
To claim the Liberals would run a scare campaign is one of the most baldfaced lies since "I thank the honorable [opposition] member for their question" in parliamentary Question Time. Scare campaigns don't need to be run based on facts, politics has moved beyond that. If a scare campaign is in the works it will go ahead regardless. Labour are still going to get called soft on crime if the Liberals think it will win them votes.
