Precisely. The precedent of "a frightened public is a compliant public" has now been set. "Climate change lockdowns" may be coming on politicians' whims, who claim to be following "the science", unless we resist fiercely, and show that we have not forgotten the tyranny of lockdowns. Remember how the Ukraine headlines followed immediately from all restrictions being lifted, so much so that they completely drowned it out? Poor old Boris never got to have his big moment of saying "it is with great pleasure that I declare all restrictions over, never to return", because it was all Ukraine, Ukraine, Ukraine. It was also ironic that we were suddenly "nudged" to take strangers into our homes, moments after being criminalised for having our own families as house guests, with some people still being pursued by the courts.
There are plenty of other times the media have cried wolf, telling us about imminent disaster which never happened. It was subtler then, but it was still deliberately frightening the public. For example: civilisation as we knew it would end on 1st January 2000, because of the Millennium Bug. Tony Blair said he was recruiting an "army" to tackle this. I wrote to him offering to get involved: the reply from Downing Street showed there were no such plans at all. The same Tony Blair who used fear of "weapons of mass destruction" for his own murderous vanity project.
"Terrorists are around every corner" since September 2001. Also "paedophiles are around every corner" has been touted occasionally.
A lesser example was the total eclipse of 1999, with lots of the language used being similar to the state of fear used this time round. Remember how absolute chaos was predicted, with all the people "flocking" to see the eclipse, and this time round it was "selfish arseholes flocking to the beaches in summer 2020"? Also, the papers were full of pictures of people wearing those "eclipse glasses": these were very similar to pictures of people wearing masks to be seen absolutely everywhere.
All this has made me deeply sceptical of everything I read in the papers, and everything that politicians say, especially if they say "something terrible will happen if we don't do this". If the media and the government keep crying wolf like this, they will have no credibility left for when it really matters.
