Confronting someone on this matter is a difficult issue and requires, as does most things, a bit of thought prior to opening one's mouth. Generally speaking, a litterbug should be called out, so I would always err on the side of letting someone know. However, if the person makes one feel uncomfortable, a/k/a unsafe, then just pick up the piece of garbage they threw on the ground and put it in a bin yourself. Maybe, at a minimum, they will learn by example.
