Starting a new character and feeling aggressive. So instead of giving the captain the papers, I sneaked behind him and started doing critical hits with the dagger! (A Khajit with both short blade and sneak as mayors, so my skill was good enough for this.)
The guy simply turned around, made me put my dagger back in my pockets (automatically, I didn't push any buttons) and gave some silly speach about letting it pass this time.

After a long time of hitting him like that (and using the console to get him away from the closet when he drifted too close to it) he died.
I took his stuff and tried to walk out, but I had to ask him about the orders to leave! After a bit of running around and punching the guard near Socucius Ergalla in the face, and I still wasn't out. Then I had the wonderful idea of checking the internet for a handy console command and the construction set for the dead captain's id. A bit of typing later, and a fully armed Imperial Templar walked out of the door.

Imagine the looks of surprise on the face of everyone.
*Hey, he's supposed to be as poor as you can get! Why is he wearing that expensive armour?! This isn't in the script!*
