To the editor: Whatever happened to Tom Sinacore writing for the Eagle? I enjoyed his articles. He tells it like it is. He is a voice for the Silent Majority and doesnt pull any punches. Is he still around? Tedd Marcel Sudbury Editors reply: Youre not the first reader to inquire. Mr. Sinacore is alive and well and writing a booklength memoir about his escapades as a New York City Police Officer that may become fodder for a future made-for-T.V. movie. He pens occasional guest commentaries here, but no longer reports regularly on our local police scene for personal reasons.
