I didn’t get a chance to do so, but I wanted to take one of the police officers aside yesterday and ask how weird to felt to sit back and allow people to have a firefight1 right in front of them. They were good folks, and managed the crowd well, even when they had to prevent people from crossing the street as the reenactors picked up their spent cartridges 2.
The image below highlights the height of my musing. Out of the context of historical reenactment, this could be an image of a potentially dangerous situation.
Context is key.
