This has long been a tactic of the left.
Think back to that racist incident on the college campus bus, where 4 black girls were victims of racist abuse. It was reported on all the mainstream media, including Fox News.
Once the facts actually came out, the leftist media forgot to tell everyone that the CCTV on the bus proved the 4 black girls were actually the ones to instigate the entire event.
The same thing with the muslim girl whose care was grafittied. It was in all the mainstream news outlets when it happened and whitey was blamed. Once the actual truth came out that she did it herself and was caught doing it on CCTV, the mainstream media forgot to tell the world that she was a lying cunt.
Rinse and repeat with countless "hate" crimes.
Cenk from TYT says he hates false flags. HOWEVER, he still doesn't correct the story when the actual truth comes out that a so called "hate" crime was nothing more than a false flag.
