I wish we could prove that they were behind them.
It does seem to be leftist misfits doing the shooting.
Any operation like this would be so sensitive and compartmentalized that the actors involved would most likely be "burned" (murdered to cover their tracks) at the conclusion of the assignment because if it leaked it would do irreparable damage to the administration's reputation. They would use the young field ops which are a little too naive to carry out the missions because they would feel honored to be asked to work on such a sensitive op not realizing they have to be burned at the end...
