I kept digging into my theory about the movie "Two if by Sea" because it was filmed in Nova Scotia and that is where some of the British retreated to after the battle at Lexington. I just came across this article about some Royal Canadian mounted police getting gunned down there this weekend. Kinda spoopy.

They said the suspect was dressed like a cop and driving a cop car.
