A day after traveling to Ferguson, Mo., Attorney General Eric Holder again pledged that the department would conduct a “thorough and fair” investigation into the fatal police shooting of the unarmed black teen Michael Brown.

“This attorney general and this Department of Justice stands for the people of Ferguson,” Holder said in a news conference in Washington.

Holder met with Ferguson officials, community leaders, and Brown’s family. He said it was apparent that residents took great pride in their town. He told them that he “personally” understood their mistrust of law enforcement.

“I went to Ferguson to provide reassurance; in fact they gave me hope,” he said.

“My commitment to them is long after this tragic story no longer receives this level of attention, the Justice Department will continue to stand with Ferguson,” Holder added. “We will continue the conversation this incident has sparked about the need for trust building between law enforcement officers and communities they serve.”
