i agree that you should never do something like that normally but dont count out the possibility that the person he's gonna roll on is a horrible person.

when someone deals drugs the tendancy is to try and turn as much of a proffit as possible, thats the way it goes and the sad fact is that there are some people out there who end up doing horrible things. hurting people and doing much worse things than slinging pot.
so you were gonna shoot someone and i know you dont want anyone to rat on you so why would you rat on someone
