Freelance writer Crispin Y. Campbell and Washington Post photographer James A. Parcell interviewed a random sampling of people for their opinions of the recent outbreak of violence in the wake ofanti-Ku Klux Klan demonstrations here last Saturday. They were asked: "What was accomplished by the incident and what lessons were learned?" Ophelia Jones, 47, waitress, of Harvard Street NW: "Nothing was accomplished. I have five sons, one of whom went down there, and he left when he saw trouble coming. I doubt that they accomplished anything. It was just a group of people who went out looking for trouble. I'm saying that the reason they went out there was to cause trouble . . . . . A group who went to break out windows and cause trouble, who didn't even know the meaning or issues of an anti-Klan demonstration -- I don't think they knew what was going on. I was very upset." Willie Vazquez, 37, District government employe, of Columbia Road NW: "It did nothing but give hype to the Klu Klux Klan. Second, it again showed to certain elements in this country that violence is not perpetrated by the Klan but by elements in the community who come in to take advantage of the situation . . . . We have a large youth population in this city that will vent its frustration and anger and that community leaders, public and private, must deal with." Richard Pasciuto, 31, wholesale food store manager in Northeast: "Basically, nothing is ever accomplished by violence of that sort except further polarizing two opposing views . . . . On Saturday, the Klan got what it wanted, to show that black people are an unruly mob. The people participating in the violence did themselves a disservice and only showed the nation what the Klan espouses is true. It is unfortunate because the majority of the people who live in Washington aren't like that." Rachel Hopp, 30, attorney, of Ontario Road NW: "I think it's a shame it happened, but not totally unexpected. It shows a lot of frustration. I think it puts the black movement back and it has had an adverse effect on how people think of blacks, and caused a loss of respect for the black community . . . .But the Fair Housing Act did pass as a result of the 1968 riots." Kwang Won Seo, 51, of 11th Street NE, grocery store owner: "Nothing was gained, not with all those damages. Nothing was learned. Riots will never accomplish anything." Joan Hopkins, over 21, school crossing guard, of Clifton Street NW: "They didn't accomplish anything and just made themselves look ridiculous by destroying property. To me it was uncalled for. They were down there for one thing and they ended up doing something else. The motive seemed to be stealing and they did what they wanted to do anyway and just used this as an excuse to do it." Allan Berger, 23, unemployed, of Clydesdale Place NW: "I was there . . . . Two things were accomplished. First, the good thing was that opposition to hate groups was demonstrated. The bad thing was that for outsiders it gave credit to the criminal faction which took advantage of the gathering . . . . I was very hurt. I think it helped the Klan more than the anti-Klan movement, to which I align myself . . . . I think we realize we have to have more control over ourselves . . . . We have to work on our unity, a lot more." Arthur Erwin, 58, carpenter, of Third Street NE: "I don't think it was worth a damn. I think it was as stupid as hell. That's what I think. It's stupid. Nothing was learned. The same thing will happen all over again. It was stupid on both sides. Barbara Humphreys, 39, librarian, of Eighth Street NE: "I think it was absurd. I think it was hooligans. There was nothing to do with the Klan. It was opportunists. I don't know if there are any lessons to be learned from this type of thing." Patricia Garrison, 26, personnel assistant, of Fort Dupont Street SE: "I don't know why they would permit the Klan to come into the D.C. area. I don't think [the Klan] gained anything by it."
