Good move. Litter attracts litter. The problem with our chicken shyte governments is they allow encroachment on laws until they are so established you can't get rid of them. It's a form of critical mass thinking. E-bikes, e-scooters, tent cities, all fit the pattern.
That’s what happened here. The police decided the tent city was a no-go location so I’m reasonably sure the inhabitants spread the word and it grew. It’s right by a nature path and that path is strewn with needles in places apparently. Someone died there last week (OD?) and before that there was a stabbing. Before that someone decided to drive over a bunch of tents. It’s a charming place.
