Can a Subway Menace Be Reformed? Yes, He Says, With Housing

Carl Beamon lumbered through the halls of John Jay College of Criminal Justice in Manhattan on a Wednesday afternoon last month.

He made his way to the computer lab, where he settled between two other students. He liked getting to campus early. He liked being among fellow students, many of them young enough to be his grandchildren.

As he settled in for class, though, his tan baseball cap stayed on his head, left to cover scars from a very different time in his life. In 1991, Mr. Beamon attempted suicide. In 2001, he tried to push three people onto subway tracks. He went to prison for attempted murder and was paroled in 2007.
