What caused the gang wars in LA between the Latinos and blacks?

The gang war between Latinos Vs. Blacks in LA was way over hyped. The media made it look like they were just killing each other just because, that wasn't/isn't the case. Yes there is tension between some Latino & Black gangs but it's nothing like the media over hypes it to be. People don't realize that most blacks & latinos in LA get along, and speaking on the black & latino gangs, it's some that have a truce with each other and even some that have an alliance with each other.
