The article points out that many protests in the U.S. went smoothly through the practice of police and protest organizers meeting and jointly managing protests, but that this practice fell into disuse after the 1999 Seattle WTO meeting in which protesters violated the negotiated terms and police responded with violence.
While some recent (and ongoing) protests have turned violent, many didn't. In the coming months we'll have time to do a postmortem. I strongly suspect spontaneous protests without organization will be found to have the most potential for violence, while those with organizers committed to self-policing and, ideally, cooperating with police will be found to have fared much better.
Individual people may be intelligent and responsible, but crowds have their own rules of behaviour and need to be managed. Protests are more dangerous when unplanned or when their organizers give no thought to self-policing.
There will always be organizers who want violence because it reliably brings press coverage and attention to their protests, but social media is also creating new problems. Coordinating a large number of people to show up at the same time and place used to take considerable planning and effort. When you have to work hard just to get the even to happen, why wouldn't you plan how it will unfold as well? Now a couple of tweets or posts on the right reddit subs will suffice. How can police meet with the organizer of a protest when it's really just some dude who had a lot of social media followers and might not even bother showing up himself?
I find it very odd that the police still cannot after all these years and with all development in surveillance tech distinguish between peaceful demonstrators and rioters. One could almost believe that they have no interest in making that distinction.
I have been in the middle of protests when I worked for Reuters and the difference between peaceful and violent is very tiny. I was in the no-man’s land between the KKK and the New Black Panthers in the wake of the James Byrd Jr. lynching and it went from frenetic but peaceful to riot in 8.3 seconds. Actual combat is a a lot less ambiguous and disorienting. Not defending police or condemning them, but when an airborne brick heads your way, it’s a pretty tall order to expect immediate and accurate identification of friend or foe.
It is fascinating to me how left wing protests seem to frequently degrade into violence. Recent case in point was the reopen protesters. I don’t think a single shot was fired by the crowd, nor were any buildings burned or looted. The Charlottesville, VA protest by the extreme right wing however is a counterexample — but it’s an exception that proves the rule. The Tea Party protests were never violent. In almost every large-scale protest that has left and extreme left wing elements, looting, fires, and violence is a foregone conclusion. It’s historical record.
It’s really tragic because pretty much all Americans were outraged about Floyd’s death, but as soon as looting, fires, and violence starts, then a large portion of the population now starts discussing and being angry about that rather than the core issue.
I'd also like to see numbers. There are a lot of pride parades, various demonstrations, women's marches etc that aren't met with violence.
I guess my point was that at a police brutality protest, you have protestors facing police which is instantly adversarial and a form of counter protest if cards are played poorly. If you have a reopen rally per the example up-thread, you're (very generally speaking) not going to have quite the animosity between them and those securing the area. And combine that with the fact that someone not wanting to rush and reopen is likely to stay at home per state instructions.
