My partner (known as dixie2mae around these parts) came across this article today and suggested I share it with everyone. Orta was indicted for what is supposedly an unrelated crime, although he claims that he was basically framed by the police in retaliation for his filming of the Eric Garner death. I honestly know very little about Orta or his personal story, so this may be true, or it may not be. Personally I would not put it past the police.
Anyway, I apologize if someone has already written about the topic.
ETA: Commenter pooltoy supplied a link to this must read article.
The above article details Orta's account of the Pantaleo grand jury (h/t pooltoy)
