What will it take?

[Magoo]

The best result would be for the protesters to fold their tents & depart peacefully, having first cleaned up any mess they've made.  Leaving could happen if bad weather continues for some time, enough to make them cold & miserable & perhaps the police are waiting & hoping for that to happen.

If police have to move them all by making lots of arrests, dismantling tents etc. etc. then that would take time & any heavy handedness won't go down well even among those of us who see this lot as misguided plonkers who've been hijacked by the extreme right nutters r' us brigade.

i see something more sinister than 'misguided plonkers' at work here.
the speed and efficiency of the supply lines in setting up, the portaloos, the stage and sound system.
it all costs and takes time to organise.
while the protestors were fragmented and incohesive the event itself was not.
the police were completely and woefully unaware of what was happening around them,
and by the time they acted the village was dug in.
