To set the story straight, as quoted in the Observer, "THE political violence that haunted the 1980 general election has evaporated."
What you are referring to happened 35 years ago. Reagan was the President of the USA and MTV did not exist yet. It is history, but since it has no impact at all on current conditions, I am not sure how "important" getting acquainted with it is.

And out of curiosity, what is the date on that High Times article? When cocaine first hit the island in the 80's - early 90's, as it did in America in the 70's and 80's, it did have its usual devastating impact on some. But Jamaicans quickly learned from their addicted friends who became what was called a "stockie" that cocaine (and crack) was not the way to live.
