I don't disagree with this, it's actually a portion of the point I was trying to make. That is, all other things equal, they should be equivalent. It's the "other things" here which may make the results different, and I'm not sure that's a bad thing.
For example, consider a parade scheduled from 11 AM to 1 PM on Sunday, known well in advance, and an impromptu protest that really gets way at some random point in the afternoon, most people didn't know about, and causes logistical problems for many people. I value and appreciate the need for both, but I also understand and support the police trying to contain and in some cases disperse (peacefully!) the second. Indeed, the anti-establishment bent the protests often have usually benefits from some police presence, IMO. It's a better story and reaches more ears.
