Five burly, casually dressed men, around 40 to 50 years old, sat in a white Escalade yesterday outside the New York City apartment building, between 24th and 25th Streets, where Katie Holmes and her six-year-old daughter Suri are holed up after Holmes filed for divorce from Tom Cruise. (What? You didn’t know?) The men, reportedly from the Church of Scientology, refused to identify themselves or roll down their windows when a reporter from the New York Daily News approached. The SUV had Tennessee license plates and the men sat with the engine idling and the AC running, getting out of the vehicle only to photograph reporters who were interviewing neighbors in front of the building. Developing.
