How do you know that the real terrorists are the ones standing next to you shouting, "Open season on cowardly terrorist scum must begin TODAY!"
Folks, we don't know for a fact who did this. And if one can envision any one group willing to do something this vile to make a point, one must accept the possability of ANOTHER group willing to do something this vile to make the first group look bad.
None of us knows who did this. Be careful of those who insist they should decide for you.
