Basicaly, i was in falkreath's prison starting the quest with siding, up until that, nothing out of the ordinary, until i was walking out of the building and one of the guards made an unique quote wich i never saw, but i was going out the door before i could read it all! All i could make out was something like this "You... you were in that..." the rest is a blank to me, but i read the word rampage. Not sure if it's related to a quest i made but i never saw a guard use this quote, and now they won't repeat it. I also never went into a killing spree of innocents, so it's probably quest related, so if someone knows this quote, can you please tell me exactly how it is? Or direct me to a page full of the guard's quote.

Just to add something funny tough, the guards of skyrim have physich powers. Seconds after i agreed to help siding, one of the guards said "i know you had something to do with siding's escape... don't deny it". Of course even tough he says it, he does nothing, top notch work there guard.

This is a list of all the phrases that guards in Skyrim say. I don't see one quite like the one you're mentioning but maybe this list will help trigger the memory.

Also, this list does contain some spoilers since it includes some lines they say only after you completely certain quests.

Here is a link to all the guard's dialog. http://www.uesp.net/wiki/Skyrim:Guard

I didn't see the quote you spoke of on the list, though.

I was checking it just now... but i can't find the word rampage in there... and i'm pretty sure i saw the guard use it in the subtitles, he sounded shocked before i went out the door... dammit, when the game does something interesting out of the blue i can't even see it...

Ok, i guess i must have misread it then... i found the quote it was related to sinding.
" You... you were talking to that murderous savage, and then he escaped. What are you hiding?"

Guess i simply saw murderous and related that to rampage... oh well.

Well it's close enough to "savage," so I see where your mind went with that one.

"You... you were talking to that murderous savage. And then he escaped. What are you hiding." Happens after Sinding escapes from Falkreath. It's at the bottom of the list.

Edit: Nvm. I'm slow

Yeah, that's the quote they say after the "interview". Funny thing happened to me when I finally got around to this quest. I walked into the barracks, approached the door and a guard to the left, seated at a table, said, "Psst! Hey, I know you! Hail Sithis!" which is right as I was head of the DB. Out of curiosity, I decided to engage him in conversation. That was enough to prompt him to say, "I know you," and at first I thought, wait, he already told me that. Then he stood up, drew his sword, and charged me with crimes against the... whatever that hold is. I had a whopping 40g bounty!
