I think restriction fatigue is becoming a big issue. To begin with it seemed like everyone I knew was basically following the rules and any transgressions were pretty minor - people having a chat outdoors on walks for example. That seems to me to have changed now, with large numbers going "ffs" and stretching or just plain ignoring the rules.
What I don't get is they knew this. They knew they'd get one good shot at lockdown with high compliance then this would happen. They needed to use that time wisely - building up the NHS, the temp hospitals, ventilator and drug supplies, training people in new specialisms to be able to support covid patients, doing mass entry level recruitment and training of auxiliaries, cleaners, admin etc so that clinical staff could be focused solely on the clinical side. Building testing capacity and a system that worked. Track and trace that works, quickly and reliably. Networks to support the vulnerable. Sorting out care homes properly - specialist teams should have been going in to every home to create tailored plans taking in to consideration the premises, staffing, patient/resident needs and so on.
It doesn't seem like they did much of that at all, at least not well. So now they're trying lockdown lite, and people aren't complying anymore.
This is not an snp bash - seems like it's been blown across the country
