[The Purge] During the purge what happens at US -Canadian border towns divided in two by the border such as Stanstead, Quebec and Derby Line, Vermont?

The town listed above have streets and even buildings like a library cut completely in half by the US - Canada border.

Other areas worth considering are Point Roberts, Washington and Campobello Island, New Brunswick

For Stanstead and Derby Line is just half of the essentially one town plunged into anarchy (Granted I doubt Derby Line would be too affected by the purge aside from some thefts and maybe 1 or 2 murders) while the other goes about business as usual?

Considering how The NFFA are a totalitarian regime, it's entirely possible they annexed those towns fully into the US- or the opposite happened.

Assuming that *didn't* happen, likely there would be a physical barrier in place that separates the two areas with only the American side allowed to do any purging.
