..a wider view of this and this..
This sculpture is one of several “interactive†monuments in Kelly Ingram Park, north of the Baptist church where a KKK bomb killed four young African-American girls in 1963. Artist James Drake’s 1991 work depicts snarling police dogs made of scrap iron leaping inward from two walls on either side of the park’s walkway. Visitors can stand between and try to imagine the terror when civil rights marchers were assaulted with the canines and water cannons — which, by the way, are also in the park, and can be pivoted to point toward a sculpture of two cowering protesters.
