I will speculate, with probably a high degree of certainty, that the woman who threw the package is white.
1) No mention was made of her race, because if it had been a black woman that would have been detailed form the first hint of this story hitting the wires.
2) She was not arrested and incarcerated, pending her complete and full payment of all costs incurred by her TERRORISTIC THREATS and ACTIONS.
My brain is in melt down that this woman was not booked and charged, and that she be made to reimburse the government for all costs involved in this stunt.
