Uprising vs. Rebellion

Upon watching the video and learning about L.A. in 1992, I now realize that the events in L.A. started out as an uprising but then became more of a riot due to the people that joined in and the chaos that emerged from this. I believe this started out as an uprising because there was injustice with the Rodney King decision, and the black race had a cause to uprise. Other races did join in because of the inequality at the time, but the main issue here was between black people and the cops. The riots turned into a crazed frenzy, which ultimately was not called for, and why I believe this has been coined the term a riot. Many people joined in on this chaos with no real cause except just for destruction. Overall, I don't think that either term if fully appropriate, but if anything this should be called an uprising due to the driving force behind why all of this started.
