I'm planning my own intervention, and its not going to be pretty, but such things never are. Its not about drugs, but it might be a nastier habit certain people need to break themselves from. I am not hopeful.
But it got me to thinking about the whole process of interventions. They usually involve either drugs or alcohol, or both. In this scene from Season 4 of The Sopranos, we see how easily the best of intentions can go awry due to the inherently unpredictable nature of such endeavors, and the people involved.
Of course, in this case, the "family" involved in the intervention attempt towards one of their members, happens to be a Mafia family, so you can expect hi-jimks on a even greater order of magnitude.
