I don't know how much racial tension goes on as a matter of course in that part of Florida, so it's hard to prognosticate. Tension in L.A. had been building long before the verdict in the Rodney King case finally caused the explosion. South Central, along with Watts, were ready to blow; the King debacle just gave it impetus. There's another difference -- the defendants in the Rodney King case were LAPD cops. This made it seem that they were part of 'the system' and 'the system' was protecting its own and perpetuating what was perceived as biased police stand against people of the black ghetto. I don't know whether the situation is similar in that part of Florida.
In a very real sense, the beating of Rodney King was not seen as anything unusual by most people in the know, certainly not by those living in South Central or Watts. What was unusual was having the video as incontrovertible evidence that the police were, in fact, racist thugs (in the minds of the residents of those areas, I mean). It gave some people an unrealistic hope that this time things might turn out differently and the 'thugs' would be punished. But then the venue was moved to Simi Valley (an egregious mistake on the part of the judge, in my opinion) and the whole thing went BOOM.
I remember hearing the 'not guilty' verdict announced the night the trial ended. I was living up in the woods in New Hampshire at the time and said out loud to anyone within earshot: "My Gawd! L.A. is going to blow." The next morning it did.
