Hell Yes!! You can’t go out after dark in the murder capital of the world!!
It's a modern trend, I think. Here in the Unmurder capital of the world, a few miles due west of there, trick-or-treating ceases abruptly at dark. This is abetted by the extended DST.
Very probably though, the cause is the same. Namely anxiety over the safety of the children.
When you have a contingent of S.S. agents, you can do whatever you want, whenever you want, wherever you want!!!
