Vincent Bevins the author of The Jakarta Method actually wrote a book about why the protest movements of the last few decades rarely achieved their stated goals. It’s worth checking out.

Not really. The overwhelming majority of those protests were peaceful. However the media latched on to the few cases where riots broke out which is pretty much what they always do.

Yeah honestly, if you’re only looking at the campaigns that led to overthrow of the government or territorial liberation then it should be somewhat self evident that nonviolent campaigns have better outcomes. They lead to less death and less destruction of infrastructure which is desirable for whatever comes next. Unfortunately, that’s not always an option for people seeking liberation.
