Frumteen. Ohr Nava is NOT for those who are in the dark alleys and the other places you describe. It is for the girl or boy who would not do those things unless they were placed in a situation where they were tempted to do so. The ability to bowl without that temptation is TREMENDOUS. I am the father of a teen. I allow my child to go bowling motzai shabbos this summer because the temptations while waiting for a lane are no longer there.
You missed the point entirely, but then again, most teens (or those who think them) usually do.
