Shirley Leung draws the wrong conclusions from the examples she cites supporting Boston’s Olympic bid (“Instead of saying no, let’s try being open to the possibilities,” Page A1, Jan. 9). The Big Dig was necessary but handled incompetently, and its multibillion-dollar overruns will be a drag on further transportation improvements for years to come. The Democratic National Convention closed North Station to the public, the rightful owners of the station. It was a mistake to hold the convention at the Garden.

The lessons from Leung’s examples are that, when the public interest is at stake, if it is not necessary, then don’t do it. If it is necessary, then keep a tight rein on the project, and don’t let the contractors run the show.

The Olympics are not necessary for Boston, and no one appears to be overseeing the interests of the public.
