You might want to look at the link at post 30. Revelations are coming out now that may question what was said in this article.
Thanks. I actually found that article the day you made your comment. I was searching where it came from, and happened upon it from Google.
I think it's interesting that this kid hasn't come forward publicly, nor has he been identified by LE, at least that I can find. I did see that the Feds are opening up a civil rights investigation, that could lead to criminal charges against the cops. I would think that it would be difficult to make that case absent a complaining witness - this young man. I'm assuming he'll be publicly identified in time, as his identity is known to police because his name was redacted from the report.
I'm also guessing that in the brief period of time that they held him, they ran wants and warrants. Since they released him, I'm assuming the kid isn't a criminal - at least not one who is currently wanted by law enforcement.
My only thought is that if the kid either had a criminal history, or was an illegal, someone from the police force would have leaked it by now, to help the two cops in the middle of the mess.
