In response to the nighttime announcement of the Ferguson verdict in which officer Wilson was not indicted, some people attacked the police and damaged property. Some experts have been critical of the decision to make the announcement at night, since the time of day does actually influence how people behave. In general, making such an announcement at night is a bad idea—unless one intends to increase the chances that people will respond badly.
Obviously enough, peacefully protesting is a basic right and in a democratic state the police should not interfere with that right. However, protests do escalate and violence can occur. In the United States it is all too common for peaceful protests to be marred by violence—most commonly damage to businesses and looting.
When considering reports of damage and looting during protests it is reasonable to consider whether or not the damage and looting is being done by actual protestors or by people who are opportunists using the protest as cover or an excuse. An actual protestor is someone whose primary motivation is a moral one—she is there to express her moral condemnation of something she perceives as wrong. Not all people who go to protests are actual protestors—some are there for other reasons, some of which are not morally commendable. Some people, not surprisingly, know that a protest can provide an excellent opportunity to engage in criminal activity—to commit violence, to damage property and to loot. Protests do, sadly, attract such people and often these are people who are not from the area.
Of course, actual protesters can engage in violence and damage property. Perhaps they can even engage in looting (though that almost certainly crosses a moral line). Anger and rage are powerful things, especially righteous anger. A protestor who is motivated by her moral condemnation of a perceived wrong can give in to her anger and do damage to others or their property. When people damage the businesses in their own community, this sort of behavior seems irrational—probably because it is. After all, setting a local gas station on fire is hardly morally justified by the alleged injustice of the grand jury’s verdict in regards to not indicting Officer Wilson for the shooting of Brown. However, anger tends to impede rationality. I, and I assume most people, have seen people angry enough to break their own property.
While I am not a psychologist, I do suspect that people do such damage when they are angry because they cannot actually reach the target of their anger. Alternatively, they might be damaging property to vent their rage in place of harming people. I have seen people do just that. For example, I saw a person hit a metal door frame (and break his hand) rather than hit the person he was mad at. Anger does summon up a need to express itself and this can easily take the form of property damage.
When a protest becomes destructive (or those using it for cover start destroying things), the police do have a legitimate role to play at protests. While protests are intended to draw attention and often aim to do so by creating a disruption of the normal course of events, a state of protest does not grant protestors a carte blanche right to interfere with the legitimate rights of others. As such, the police have a legitimate right to prevent protestors from violating the rights of others and this can correctly involve the use of force.
That said, the role of rage needs to be considered. When property is destroyed during protests, some people immediately condemn the destruction and wonder why people are destroying their own neighborhoods. In some cases, as noted above, the people doing the damage might not be from the neighborhood at all and might be there to destroy rather than to protest. If such people can be identified, they should be dealt with as the criminals they are. What becomes somewhat more morally problematic are people who are driven to such destruction by moral rage—that is, they have been pushed to a point at which they believe they must use violence and destruction to express their moral condemnation.
When looked at from the cool and calm perspective of distance, such behavior seems irrational and unwarranted. And, I think, it usually is. However, it is well worth it to think of something that has caused the fire of righteous anger to ignite your soul. Think of that and consider how you might respond if you believed that you have been systematically denied justice. Over. And over. Again.
