That stuff with Mark was normal high school shit until his dad gets word or Phil gets word and has to do something before the boys look week .
If not for them growing up in a crime family it would have been regular school yard shit !
And they always make Chris look like a angel and he was right there for years is was not until a certain situation he decided to bail .
The Feds make him look clean cos they could not get nothing on him Chris was / is very shrewd !!!
