Michael Brown’s parents said Wednesday that they are disappointed that the Justice Department decided not to seek federal civil rights charges against Darren Wilson, the white police officer who shot and killed their teenage son last summer in Ferguson, Mo. However, they expressed hope that Justice’s scathing report on the Ferguson Police Department will lead to other changes, which they said would mean their son did not die in vain.

“Today we received disappointing news from the Department of Justice that the killer of our son wouldn’t be held accountable for his actions,” Lesley McSpadden and Michael Brown Sr. said in a statement issued through their attorney’s office. “While we are saddened by this decision, we are encouraged that the DOJ will hold the Ferguson Police Department accountable for the pattern of racial bias and profiling they found in their handling of interactions with people of color.”

In addition, Brown’s parents said they hope this official response will help promote changes nationwide.

“It is our hope that through this action, true change will come not only in Ferguson, but around the country,” they said. “If that change happens, our son’s death will not have been in vain.”
