Hillary Rodham Clinton says the fatal shooting of an unarmed Missouri teenager and the violent protests that followed resulted from frayed bonds of trust in his racially divided community.

Thursday's remarks in San Francisco were the former secretary of state's first comments about Michael Brown's Aug. 9 death in the St. Louis suburb of Ferguson.

As a potential Democratic presidential candidate, Clinton has been criticized for waiting so long to talk about the black teen's shooting by a white police officer.

In a speech to a technology group, Clinton criticized the shooting and the numerous tense confrontations between protesters and heavily armed police.

She says U.S. streets shouldn't look like war zones.
