As US involvement in Vietnam grew , Dellinger applied Mahatma Gandhi 's principles of nonviolence to his activism within the growing antiwar movement . One of the high points of this was the Chicago Seven trial over allegations that Dellinger and several others had conspired to cross state lines with the intention of inciting a riot , after antiwar protesters had interrupted the 1968 Democratic National Convention in Chicago . The ensuing court case was turned by Dellinger and his co-defendants into a nationally-publicized platform for putting the Vietnam War on trial . On February 18 , 1970 , they were acquitted of the conspiracy charge , but five defendants , including Dellinger , were convicted of individually crossing state lines to incite a riot
