As I've watched the many protests on TV lately, I've been wondering - do protests ever accomplish anything? I kind of understand why people protest; to show dissent for the most part. This is fine and I support freedom of speech for whomever. However, I was just curious if anything actually comes out of it. Is it productive or does it just make people feel better? Is it less reasonable to protest post-decision (i.e. after we are already at war) than it is before hand? Do laws actually get changed because of protests? I'm not trying to be contrary - I'm just curious about the outcome of these protests, especially the ones that come before a decision is made.
