All they need is a reason to investigate, and a racial slur is the trigger. That's why everybody is bending over backwards to find one, and they will. This is the Florida Ballot fiasco all over again, and it's a national disgrace.
On an unrelated note, is anybody else having problems with the server? I can't even get into my pings...
They can fabricate a reason to investigate. My point was that investigation, regardless of the outcome (e.g., there is clear, unequivocal evidence that Zimmerman was uttering a steady stream of racial epithets), is useless (other than the obvious propaganda value, and ginning up the desired mob violence) without a crime to attach it to. There has to be a manslaughter, assault, or similar conviction, by the state.
