President Trump recently made an offer to National Football League players like us who are committed to protesting injustice. Instead of protesting, he suggested, we should give him names of people we believe were “unfairly treated by the justice system.” If he agrees they were treated unfairly, he said, he will pardon them.

To be sure, the president’s clemency power can be a valuable tool for redressing injustice. Just look at Alice Johnson, age 63, who was serving a life sentence for a nonviolent drug conviction until her sentence was commuted by President Trump. He should be commended for using his clemency power in that case.

But a handful of pardons will not address the sort of systemic injustice that N.F.L. players have been protesting. These are problems that our government has created, many of which occur at the local level. If President Trump thinks he can end these injustices if we deliver him a few names, he hasn’t been listening to us.

As Americans, it is our constitutional right to question injustices when they occur, and we see them daily: police brutality, unnecessary incarceration, excessive criminal sentencing, residential segregation and educational inequality. The United States effectively uses prison to treat addiction, and you could argue it is also our largest mental-health provider. Law enforcement has a responsibility to serve its communities, yet this responsibility has too often not met basic standards of accountability.
