It does not matter how old or young one is. If you do something wrong and you know that what you are doing is committing a crime (especially if many signs are posted all over the place) you take your lumps.
In fact, the older you are the more you should know better! So with this in mind if your sixty I say LIFE IMPRISONMENT! The only possibility for parole is extensive garbage pick up and school appearances teaching the young about how littering is next to homicide. It makes sense.
