How does this work for ISIS?
If their lone mujahid does not get credit for the killing, if the deaths are chocked up to random violence caused by the Michael Brown controversy, how does that spread fear of Islamic terror?
Those who understand Islam for what it really is, based on it's 1400 year legacy of bloodshed and terror will recognize it.
Those blinded by fear, wishful thinking, or utopian ideals will continue to live in denial.
