The George Zimmerman verdict is in.
And so is a palpable sense around the nation that the man who was found not guilty of murdering Trayvon Martin may himself be in trouble.
Numerous reactions over Twitter and other social networks warn Zimmerman to watch his back.
Will someone's idea of vigilante justice lead to another lost life in this case?
Clearly afraid of just such an outcome, President Barack Obama took the unusual step today of an issuing a statement in reaction to the verdict.
