CAMBRIDGE, Mass. AP – The 911 caller who reported two men possibly breaking into the home of black Harvard scholar Henry Louis Gates Jr. did not describe their race, acknowledged they might just be having a hard time with the door and said she saw two suitcases on the porch.

Cambridge police on Monday released the 911 recording and radio transmissions from the scene in an effort to show they had nothing to hide, but the tapes raised new questions about how and why the situation escalated.
