Cambridge, Massachusetts police have dropped charges of disorderly conduct against Harvard University professor Henry Louis Gates, calling the incident of his arrest on July 16 “regrettable and unfortunate.”

Gates was arrested at his home in the Boston suburb last Thursday after a woman called police to report that someone was trying to force himself into his house. The incident had raised claims or racism by Gates, who is black, as well as continuing the debate on “racial profiling” by police. Gates told the Washington post he was “outraged that this could happen to me in my own home.”
