In an ideal world, Dominique Strauss-Kahn, the former managing director of the International Monetary Fund, would have been introduced to Mortimer Matz before his arraignment on Monday...But Donna Lieberman, executive director of the New York Civil Liberties Union, said: “The French have every reason to be indignant about this perp walk, and New Yorkers have every reason to be indignant about every other perp walk. It’s a way for the police to try their case in the press and to get the intimation of guilt by virtue of an arrest. The question is, does it poison the right to a fair trial? And that depends on each case.”
