In the category of "Everyone knows we still do this"

Not surprisingly, prosecutors in the south are still doing a bang-up job of keeping blacks off juries.  It's allegedly against the law to strike jurors solely on the basis of race, but it's really easy to do it as long as the prosecutor can come up with any reason that doesn't explicitly mention race.  Maybe we aren't all whole and healed on race issues just because we have a black president now.
