As a 'middle-class, law-abiding citizen', I need to have confidence in the police - indeed if they've lost the confidence of people like me then they're really not fit for purpose.
Sadly, over a prolonged period, I've watched so many Police Forces behaving so badly whilst theoretically 'maintaining public order' that I wouldn't trust them to behave well in any situation.
This was an easy target - so they leaned on the organisers and were then excessively heavy handed with a crowd of essentially peaceable women.
Compare and contrast with their feeble/inert responses to sundry other pevents over the period of lockdown - where were they at the many funerals where Travellers ignored all restriction, where were they at the BLM and anti-mask demonstrations? The answer is that they were cowering in their vans, hiding at their HQs and doing nothing.
If they had stamped on every illegal gathering throughout lockdown, then they would have been justified in breaking up this one - but we all know that they pick and choose their targets very carefully.
It's UK Policing in a microcosm - always happy to make life difficult for people who can't (or won't) fight back, always shirking responsibilty when it comes to the hard stuff.
