You know what George, I just don't see why whoever you claim is responsible would go to so much trouble. If one can accept that the powers that be are trying to poison us (playing the devils advocate here for arguments sake), it would be much easier and controlled to target people through food or water. If they are spraying over populated areas on purpose, they are also contaminating resources that would be left for them after the die off. Why would they shit in their own water supply, why would they poison the soil and why would they risk contaminating people of their own in the process. It just doesn't make sense because it is impossible to target anyone with accuracy.
