I agree it is being used to reduce freedoms, but I disagree that the parallel to terrorism is very good. Firstly, the risk from terrorism was always going to be sporadic and focused -- it is/was never an effective application of 'force'. For that you need a WMD arsenal like a State. COVID is directly and effectively killing people in massively higher numbers. Secondly, terrorism mitigation was always justified using details and intelligence that the people asking for power (military, intelligence agencies, boarder enforcement) would refuse to share. The public would not be privy to the justifications in the interests of National Security. Again, with COVID, we instead are getting statistics summaries from the government but they are being sourced from public sources of civilian interaction, namely hospitals, research labs, universities. The public can second-source and confirm the justifications. The interventions are currently being couched as temporary with some caveats regarding medical research and immunity. If COVID interventions become overly protracted, we the public can protest along with the current Trumpian crazies (who have the right very basal idea but are utterly confused and probably co-opted with regard to who they are shouting at and when they should have started shouting.) Terrorism threat assessment is privileged process. Quite different IMHO. Unfortunately only "time will tell" if COVID morphs into this secret control state in some way, currently it's all open-source. Until then, all power to the medical and epidemiology bodies and I will shout at anyone getting in THEIR way.
