It’s just a law. Rulers don’t need to obey the law. Just their subjects.
Never mind they aren’t rulers. They are public servants. And when they don’t obey the law it becomes obvious they wish to change the relationship between servant and master.
Had the troops put on a reflective vest over their civilian clothes and directed traffic as civilians I wouldn’t have a problem with it. But they didn’t do that.
It sounds like some officers are taking it seriously but don’t expect most government officials to care in the slightest. They might need those troops for controlling the serfs someday.
