Is there any context here that demonstrates Holder meant anything other than the Justice Dept. Attorneys?
If you are talking about his use of "my people", it's not attorneys he's talking about.
"Think about that, when you compare what people endured in the South in the 60s to try to get the right to vote for African Americans, and to compare what people were subjected to there to what happened in Philadelphiawhich was inappropriate, certainly that to describe it in those terms I think does a great disservice to people who put their lives on the line, who risked all, for my people."
He clearly means black people when he says "my people". Certainly no one was putting their "lives on the line in the 60's" for Justice Department attorneys. An argument could be made for the National Guard, but Holder would never make it.
