As it says at the end of the Goodfellas movie,
Henry got pinched again in 1987 for conspiracy to supply narcotics. Apart from that he was still
clean at the time of the 1990 movie.

It's this incident and his relentless thirst for publicity, post the book and movie that got him thrown out of the witness protection programme.

To answer Family Honour's point - I don't think the Feds would have him back.

Hill has experienced a lot of drug and alcohol
problems over the past 20 years. I believe he claims to be currently clean and says he helps former addicts under a different name.
Kind of ironic given that he got where he is getting people hooked on this shit.

As old and wise members of the board have said
already, I think he's a pretty unpleasant guy in practice. I used to follow his website a little
(not in last 6 months) and it always seemed disorganised and as if nothing changed month to month.

Whether you want to moralise about him being a rat or not - putting that aside he's not the
Ray Liotta version.

We didn't get to see the inner scumbag.

Incidentally, I still think Ray Liotta did a superb job - we had to have some empathy with the guy. It's a shame Ray probably will never equal that great performance.
