There was the weird SS car chase in VA/MD with someone maybe impersonating a Marine.Before the holidays.
Separate from the Marine Barracks shooting.
What about the two incidents where people stepped in front of the motorcade en route to a rally?
One more - I have this suspicion there is one from just before Inauguration day. Might be in the page/strok text msgs, but something was definitely up for S Rice to send a note to file day of inauguration.
