Peaceful protestors should never be prosecuted. Why is that even up for debate? It’s the protestors who destroy, litter, and cause public disorder who should be prosecuted, regardless of what they’re protesting against. Someone throws soup on a painting in a museum? Jail. Someone throws paint on a person? Jail. Someone attacks a police man? Straight to jail. Someone just putting up a banner and raising awareness around an issue? Absolutely fine and many times even needed!
