There is a large amount of information available on the 1992 Los Angeles riot-- films, government documents, books and articles. If you have access to a public or university library, searching 'Riots--California--Los Angeles' and limiting the search to things published after 1992 will bring up some excellent results. I'll include a list of some of the films and books I found using that search strategy, but I would encourage you to explore further, by examining the sources cited for some of the resources I'm listing.

'Explores the embittering effect the Rodney King verdict and subsequent April 29, 1992 riot had on Korean American women shopkeepers who suffered more than half of the material losses in the conflict. Film underscores the shattering of their American dream while taking the media to task for playing up the "Korean-Black" aspect of the rioting.'
