Rebellion? Drugs/alcohol? His parents are strongly Evangelical Christians. It's not his first brush with the law. We used to call similar behavior "Preacher's Kids."
If he's 28, though, maybe he simply has the typical millenial attitude toward conventional authority. Only he knows why he did it.
I would say that with their millions the Palin’s should have had Track in psychiatric counseling which they can well afford but what they really should have done is get him out of Alaska and situated someplace else.
Alaska is a weird place with a strange conglomeration of really strange people. Mr. GG2 lived there for a short time and his rental house was on the lake in Wassila right down the street from the Palin’s. He helped Todd load up his float plane a couple of times and briefly met Sarah once at the dock. He said the first rule of Alaska is you never ask anybody about themselves. Its a place with a lot of drugs, booze, hillbilly types and skeezy people who don’t want to be found. Family feuding is also big in Alaska. They need to remove him from the mix.
