Nobody would ever pay attention to a protest if it wasn't at least moderately disruptive.
Of course but at what point does a peaceful protest become too disruptive? Like, aside from this protest, when would anyone who blocked traffic on a main thoroughfare not expect to be swiftly arrested?
Protesters often break laws, usually intentionally. There's a famous essay about it which most of you are probably aware of but are presently ignoring, "Civil Disobedience." To do civil disobedience honorably, protesters 1. can't resist arrest, they should go peacefully if arrested, and 2. stay nonviolent.
So, the protests in Cleveland and Cincinnati were pretty damn successful and honorable protests in that they stayed nonviolent and nobody resisted arrest, and I commend them for it. Looting, rioting, all that stuff in Ferguson, that's no good, but that didn't happen here.
You and the others who have pointed it out are absolutely correct that blocking the highway is illegal and aside from this protest, if somebody did it, they would be swiftly arrested. You'd have to call the police or the FBI and ask them why they didn't arrest these protesters. Hint: It's because it would make them look bad. Called a "dilemma action" and also a common protest dynamic.
(EDIT: Reading up on the Cinci protests, looks like 15 arrests after people got on 75, but don't see anything about resistance to arrest)
I don't know all the facts but I think the grand jury in MO made the right decision, and that Wilson probably feared for his life. He doesn't seem like some kind of white supremacist killer to me, he seems like some kid just trying to do his job and stay alive. Regardless, it's obvious that there are huge systemic problems way above Wilson and Brown that led to this. Black frustration with policing policies and practices is well justified. I think people should stop worrying about indictments and convictions so much and start worrying about changing the circumstances that led to the event.
For that reason these protests are a good thing. There's no such thing as bad publicity and since everyone in Ohio is going to be discussing the protests today, I'd say that's a win and a hopefully a move towards substantive change. Either change through legislation, but that's not even necessary. Police departments are going to tweak their policies all across the country to try to avoid a Ferguson, possibly innovate and come up with new solutions. So the battle is already won in that regard.
Now, if you're going to riot, which is different than protest, if you're going to destroy innocent people's property, than not only is that just wrong, you are going to lose the battle of public opinion, so hopefully those idiots stop doing that.
