Imperial Guard behavioral issues
In the above quest, the Imperial Guards will arrest me when I pick up the scrolls that Galbedir stole.
it is also possible to steal items in the guarded areas. To accomplish this, pick an item — the Limeware platter on the shelf next to Socucius Ergalla is recommended — and immediately drop it on the floor. The guard will rush over, reprimand you, but will not issue you a bounty. After saying goodbye, simply pick the item back up. You can do this with multiple items at a time by entering the menu screen.
In Morroblivion, they will issue you a bounty!
Also, the backdoor to Arrille's Tradehouse is not locked, giving access to his entire inventory.
