Anderson : what's the fuss about "letting him go"?

M.K. Rasgotra seems pretty sensible in this interview - http://beta.thehindu.com/news/national/article472296.ece

If Anderson wanted to come to India voluntarily, he obviously would want to go back! What's the fuss about "letting him go" that the press and opposition has created.. If he came to India after being promised safe passage, how can u think of arresting him.. And why would he come without being promised a safe passage?

Am I missing some point?
