We should make an effort to differentiate between marching, civil disobedience, and looting. They are different things, in the same way that admirable policing and excessive force are different things. After all, our arguments are only as strong as our ability to distinguish and analyze facts, instead of lumping generalizations together. To complain about marching, civil disobedience (i.e., blocking traffic) and looting all in one breath is imprecise.
Most would agree that peacefully marching in designated areas is appropriate and sometimes effective, because no one is breaking the law and sometimes people in power listen to marchers. Most would agree that looting is inappropriate because it is breaking the law, specifically committing an intentional tort or crime against another individual, and nobody listens to looters (because they are not asking for anything, and they have no credibility regarding laws).
Non-violent civil disobedience is a bit more controversial. It usually involves breaking the law or at least societal rules. Examples include 1) blocking traffic, 2) placing yourself where authorities say you should not be, 3) boycotting segregated busses, 4) sitting-in in a segregated restaurant. However, civil disobedience does not involve an intentional tort or crime against an individual. Civil disobedience does involve inconveniencing others. A current complaint I hear about protesters blocking streets is that it inconveniences white and black people alike. The inconveniences are often frustrating. Sometimes, they have serious consequences. A black or white person stuck in traffic on a blocked road could be late to work and get fired. An emergency responder might be delayed from responding to a black or white person’s medical emergencies. These consequences are real. They are also unintentional. But people bring up these consequences and say, “see, your civil disobedience is not helping. You’re hurting your own people and your own cause.” This sentiment ignores the fact that the very reason people are protesting right now is because of widespread, deeply felt injustices that result in systematic oppression and an epidemic of deaths in black communities.
Even if you don’t think racism is a problem, enough people do that they will stand on the freeway and risk arrest, tear gas, and death themselves to tell others that it is a problem, so maybe we should listen. During the Montgomery bus boycott, which went on for months, many black people complained, Many lost jobs. Many were harassed on the streets as they walked. Many yelled at their leaders and said they should quit. When protesters staged sit-ins at segregated restaurants, it was all kinds of inconvenient to black and white people. It increased racial tensions a lot. People got hurt and died. However, large groups of people decided then that it was important to interrupt the day-to-day lives of white and black people in an inconvenient way to call attention to the enormous problem of racism that is largely ignored by those who don’t suffer its consequences.
Though looting has never produced any societal changes, civil disobedience has produced just about ALL of the societal change for people who are in positions of low power. To say that protestors should not march in or block the streets because a large number of them ARE experiencing oppression, injury, and death, just because a few people MIGHT indirectly suffer unintended consequences really ignores the legitimate concerns of the oppressed.
