All that "troubled" entails. My son knew him. You know the old saying, "You can take the boy out of the ghetto, but you can't take the ghetto out of the boy?" Single-parent home. Lived in the rough parts of town until Hollywood came knocking. I believe it was a policeman who helped him get the part in The Client, actually. Or a truant officer; or something like that. My heart goes out to his mom.
It is a shame.
However, I grew up on the wrong side of town, had a pretty much absent father for most of the time, a wholly incapable mother, and lots VERY bad influences. I knew many weak-willed people who failed, but there are many who go through those conditions and yet through hard work and self-discipline, make it in the world.
The point: Those conditions are an excuse not a reasoned explanation.
