In a peacetime, urban, non-military context, how often were swords drawn in an unpremeditated context? Ignore any context in which an individual is directed to draw a sword, or contexts like a duel where drawing of the sword is announced. How frequently was the sword drawn in drunken brawls, in self defense, in the heat of anger, etc. ( I suspect there is a formal legal term for such action, but I don't know it).
I see many period pieces in which swords are worn. I am not sure how accurate they are with regard to them even being worn but what I am really wondering about is how commonly at any point in history using them to settle arguments as opposed to dueling was. It seems like in cities, resorting to a deadly weapon would have been a big deal even in the middle ages but I don't know.
EDIT: The question seems to imply that it was at some point usual but I try to explain that I can accept it never was usual. What I am interested in is, was there ever a time when swords were used as frequently as say fists were in 19th century USA and this was considered okay because both parties were armed or was use of deadly force a very serious legal matter always and if not, when it did become so? Maybe people in England did not carry swords as much as movies would imply.
