Cocaine Cowboys, Picard, Leary...

[Triple7]

Some of you might have seen the documentary or film, Cocaine Cowboys. One of the most evil characters in the documentary is Griselda Blanco, also known as la Madrina, the Godmother, the Black Widow and the Cocaine Queen of Miami. She had lots of people murdered and lots of drugs trafficked.

William Leonard Pickard is currently appealing a 2000 conviction in which he was sentenced to 2 concurrent life sentences without the possibility of parole for conspiracy to manufacture LSD at a converted Atlas-E nuclear missile launch facility in Kansas. This guy is not a Cocaine Cowboy.

Another person that has nothing to do with the Cocaine Cowboy is Timothy Francis Leary. The story with his is quite weird. Anyway, he got first senteced 30 years when his daughter was caught with marijuana at the border to Mexico. Then 4 years later he was released since prisoning him was unconstitutional. Later, president Nixon had labeled him "the most dangerous man in America" and in 1972(?) a judge sentenced Leary to 95 years in prison, and then he was again released from prison 1976.

Something that is interesting, is that many of the Cocaine Cowboys, were released after ~20 years, this includes Griselda. What makes that these Cocaine Cowboys stay less in prison than others who committed less crime than them?

The story about Leary is interesting. My english sucks, so I don't understand what I read about him. But anyway, why was he released 1976? And Pickard, it seems to me that he got more severe sentence than the Cocaine Cowboys.

Any suggestions or ideas why some of the "Cocaine Cowboy" members got out after 20 years? What where their original sentences?
