"I conjecture, based on the use of the octagon. The octagon, or octagram, is a mystic figure, the subject of some speculation, as it has eight termini or points, yet is formed of a single, unbroken line. In various contexts it is often said to represent the concept of regeneration. Given terrorists with symbols of regeneration, or rebirth, and the color white, which may be said to represent death or purity, I conjecture that racists may be involved. And what are racists but those opposed to metahumans?"
