Charles Preston wants to make one thing perfectly clear.<br />Worries that protests against police might turn violent had brought a member of Congress out onto the pavement in Minneapolis and prompted a pleading press conference from Chicago Mayor Rahm Emanuel Tuesday.<br />But Tuesday night's message was not "all is well," say Mr. Preston and others involved in the protests.<br />For instance, the arrest of aspiring Chicago poet Malcolm London - who once appeared at a TED Talk with Bill Gates and John Legend - was on "trumped up charges," says Preston.<br />The incident speaks of the fraught relationship that remains between the black community and police even as police take historic steps steps to rebuild trust.<br />In Minneapolis, five Black Lives Matter protesters were shot Monday night - though not seriously wounded - at one of a series of nightly rallies outside the Fourth Precinct for Jamar Clark, a black man fatally shot by police on Nov. 15.
