I'm waiting for the upsurge in banditry - Aerenwe, where only the sheriffs and criminals roam armed and marks are easy prey... In the UK its mostly just criminals and cops nowadays that go armed, but back in the day just about everyone did - any serious travelling required weapons.
And what is a weapon? Every field hand has mallet, scythe, knife, etc, etc - strictly interpreted the village blacksmith, the butcher, etc, etc are all going to be in pokey.
I'm waiting for the first knight, lordling, etc to be arrested - unless Aerenwe is going to close its borders then all those with the right to bear arms from nobility, order of knighthood, etc are going to get very annoyed very quickly... is the count of such and such to be declared a criminal merely for riding the imperial highways? Is he some common blackguard to be deemed threat to the crown and so barred means to defend himself? Why how dare some yokel sheriff cast aspersion upon the count's honour by implying that he might engage in brigandage or some such with his arms!
Twentieth century thought in a quasi-medieval setting often has interesting consequences...
