[Star Wars] Im a smuggler in the cantina in Mos Eisley when Obi Wan uses his lightsabre. Is the subsequent silence in anyway due to everyone being in shock at seeing an “extinct” jedi or just shock at seeing an old bald human attack a walrus with a weird laser sword?

I suppose the question is whether people in the outer rim knew about the history of the jedi/sith and the significance of Obi Wan publically using his lightsabre.

Most people probably just went silent because someone just got de-limbed; there's a similar silence after Han Solo fries Greedo. Even for Mos Eisley, that kind of stuff draws attention, y'know?

But there probably were a few people in there who'd heard the legendary tales of Jedi, and put two and two together. Remember, Jedi were an absolutely minuscule fraction of the galactic population... but their impact was outsized for their numbers.
