Two wrongs don’t make a right. Parents have been teaching their children this truth for generations. They also probably taught them that violence begets violence. But people too often forget those lessons, as we’ve seen in the aftermath of the George Floyd killing in Minneapolis, and now the shooting of Jacob Blake, a Black man shot in the back and probably paralyzed by Kenosha, Wis., police this week.

The anger and frustration of the Black community over these kinds of incidents is understandable. We respect the right to march in protest of these. But to commit violence, to attack police, to loot and burn down businesses that serve the affected community is wrong. It doesn’t right the wrong that sparked the demonstrations in the first place.

And it is also wrong for armed vigilantes, spurred on by social media postings, to show up at Kenosha. On Tuesday, two protesters were killed, another injured, and a 17-year-old vigilante with an assault rifle was arrested a day later for firing at the crowd. He faces first degree intentional homicide charges.

Add them all up, and nothing that was done in Kenosha earlier this week makes anything right. Violence has only created more violence. We need to learn to break that cycle.
