I think the Nazis figured out how to privide security on freight trains against everything short of Patton and the 8th Air Force.
You can ride the “Hiawatha Trail” bike route on the abandoned Milwaukee Road rail line in Mullan, Idaho. There are lots of historic signs along the way. One shows the train security used in WW II. Armed guards were on all the trains as well as stationed at all trestles, bridges, and tunnels.
We are fighting a two-front domestic war: one against the southern invaders and the other against organized crime of all types.
It’s long past time we had “shoot to kill” standing orders. Public safety and tranquility will not be restored until then.
