Street preacher Joseph Maldonado has sued the City and County of Denver over its refusal to allow him to spread the word in high foot-traffic areas of Red Rocks Park back when there were high-traffic areas, that is. Mr. Maldonado is not seeking to go into the amphitheatre. He s not seeking to go into the event. He wants to be in part of the park where people are already free to be, says Nate Kellum, a lawyer with the Memphis-based Center for Religious Expression, which filed suit in the U.S. District Court of Colorado on Maldonado s behalf. There s no question that if he were just standing there, he would be left alone, but once he starts trying to communicate a message, he gets shut down. And that s what we think is unconstitutional.
