It's what happens when those in charge lose the trust of those they are supposed to be leading. Any fool would know this and quite a few behavioural scientists too. Watch how the rate of people sticking two fingers up to the lockdown rules increases. All the good achieved by people will be undone because Cummings has been seen to not only get away with but be held up as an example of a proper father for breaking the rules
The bottom line is this. Many countries including our own are introducing apps to save lives. That's it in a nutshell. I think we all agree reducing deaths from Covid 19 is fundamentally good idea.
Whataboutism is no excuse for not trying save lives of the old and vulnerable, potentially including people close to us.
Anybody not downloading the app is no better than idiots like Cummings bending the rules (at best) of the lockdown and thus risking more lives lost.
