This prediction was noted in the Navy Yard Shooting, it could questionably be talking about this situation. The Prediction reads:
Notes on 8-22-13 I had a vision that a gun was brought to the white house. Perhaps a threat to Washington state or Washington DC. You did get the impression it was only a threat, its success in question.
Notes on 7-9-13 11..11 (big and bold) ..9:24.. 10:03..1:11..
This is new, they haven’t done this before. It would be awesome to believe these are dates, or it could be countdowns, they were presented on a clock.
