How Could This Have Happened?

Convinced that no good can come of ignoring or forgetting a shameful aspect of American history (some 5,000 murderous, illegal lynchings, mostly of African-American males, from 1882 to 1968) the National Underground Railway Freedom Center has taken a traveling show that sometimes elicited anger in earlier venues and hopes to make it a means of furthering understanding rather than undermining it. 'Without Sanctuary: Lynching Photography in America' opened last week and runs through May 31.
