If you moved out of LA 20 years ago and lived there for 15 years you would not have lived in LA at the time of Rodney King incident and the LA Riots which was in 1992. As such you have no basis or credibility to make commentary and comparisons between LA before versus after the Riots. As someone who was there before, during and after I can say you have no idea what you are talking about. There was no momentous shift or even appreciable difference in LA in the aftermath of the riots. Further the "multicultural aspect of Los Angeles" did most certainly not get "blown to pieces." The weeks after 9/11 the palpable feeling was one of introspection, unity and kindness. So much so that the joke was it was starting to make people uncomfortable.
