Before Philando Castile, Alton Sterling, Michael Brown, Eric Gardner, Freddie Gray, and Trayvon Martin became household names that lit the #BlackLivesMatter movement, there was Cheryl Green and an active murderous campaign against African Americans that has been going on for over 20 years — but it's not being executed by the police.

A federal indictment against seven Latino gang members from Southern California was unsealed on Thursday, revealing an active and organized effort to firebomb housing projects occupied by blacks to drive them out of Southern California, the Los Angeles Times reported.

Prosecutors claimed that the gang members broke the windows of three homes with black families living in the Ramona Gardens public housing complex in Boyle Heights, California, and threw Molotov cocktails inside on May 12, 2014.

According to Eileen Decker, U.S. attorney for the Central District of California, the homes contained sleeping children and were chosen specifically because the gangs were hoping to drive blacks out of their communities.

Attacks like this have been going on for more than 20 years with little to no coverage from the mainstream media.

Starting in 1995, the Los Angeles Police Department reported that Latino gangs populated by a significantly large number of illegal immigrants were working on eradicating black citizens from Los Angeles starting in the Normandale Park neighborhood.

Intelligence Report detailed in 2006 that godfathers in the Mexican Mafia had put out orders for the affiliates in the streets to terrorize and kill black families, including 14-year-old Cheryl Green who was shot to death while riding her skateboard.

The Southern Poverty Law Center, a group that tracks hate crimes in the U.S., described the actions of Latino gangs in Southern California as "ethnic cleansing."

"A Latino street gang leader and his son were sentenced in federal court Monday to lengthy prison terms for their role in a years-long campaign of racist terror and ethnic cleansing targeting African Americans in and around Los Angeles," the SPC stated.

Major outlets and groups, besides the Los Angeles Times and the Southern Poverty Law Center, ignored most of these crimes. But African Americans noticed and left L.A. in droves. Since 1990, the black population dropped by more than half.

Irene Verga, one of the oldest black residents of the Ramona Projects where the fire bombing occurred, told the Times that gang activity has dropped significantly since then because the police increased their presence in the community.

Despite the narrative being spun by pundits on cable news, law enforcement isn't responsible for blacks being terrorized and killed. They're the only thing preventing racially motivated murder in southern L.A..
