The media doesn't help minorities. Tha't's how the "knockout game" became a thing. That is the only propaganda I see. The media had fukking RACISTS on the television fomenting a race war during the "knockout" hysteria. You say it was the media that picked up Trayvon, but actually it was small black media and Twitter users that first disseminated the story and bombarded giant media groups until those groups picked it up. There was no "propaganda" around trayvon. The essential story was always the same; Zimmerman racialy profiled Trayvon, racists defend him, poor justice system exonerates him and racists cheer a young blacan's death. This is reflected in the facts, and is not propaganda to anyone but racists,
who just like that Trayvon was murdered for being and uppity in the first place.
