"It is striking to me," Chang continued, "that you did not bother to 
report this serious crime to the magistrate! For some time now we have been 
reviewing this tape, wondering why the victim—a respectable 
gentleman—did not step forward to assist us with our inquiries. So much 
effort wasted," Chang fretted. Then he brightened up. "But it's all water 
under the bridge, I suppose. We have one or two of the gang in custody, on an 
unrelated crime, and now I can charge them with your mugging as well. Of 
course, we will require your testimony."
