Ohhhhhhh.. THAT's where he messed up
Here I am thinking he messed up by being involved in an execution style murder in the first place
I'm not condoning what he did, he should've just told dude to stay away. Given the circumstances though, he got people involved when it wasn't necessary, and a prime example of this is his fiancee who allegedly aided him in hiding evidence. The fact of the matter is he's about that life and its evident based on prior conduct involving him, and since this is the case he should've reconsidered doing in it all together in the first place, or if he was going to do it how not to get others involved (as wrong as that sounds).
