Torah dedicated near Trade Center

Torah Scroll completed in memory of 911 victims near the WT Center site.

From Downtown Express :

Assembly Speaker Sheldon Silver, right, inscribed a lamed, the last letter in a new Torah at a ceremony across the street from the World Trade Center site last week, before the start of Rosh Hashanah, the Jewish new year. The Torah will be for the Soho Synagogue, which Rabbi Dovi Scheiner hopes to open within the next few years at an undetermined site. At left, is scriber Chilik Winfeld, who wrote almost all of the books 300,000 letters. Mayor Mike Bloomberg scribed the books first letter. The ceremony, which honored those people killed at the W.T.C., was held in the Liberty St. apartment of Daniel and Sonia Kaner and also drew Stefan Pryor, president of the Lower Manhattan Development Corp. and architect Frederic Schwartz, who designed the Whitehall Ferry Terminal in Lower Manhattan.

Is Bloomberg, dating a non jew allowed to write an oys (letter)?
