The murderer guild in a previous episode was flagged orange despite red being the killer color, so yeah, it's definitely possible that someone could get blamed for a murder they didn't commit.
Anyway this episode was ok. It seems like these short stories are being told out of order, because Kirito isn't using the sword he got from the blacksmith girl and Asuna jabs him with a joke about not associating with other girls. Asuna acts out of character in the scene with the bodyguard, literally cowering behind Kirito and passively acceding to the bodyguard's rough handling until Kirito intervenes. She's his superior, she's stronger than him, and she left her passive shell quite a while ago in the story, there's no reason for her to be acting like this. Him being a man or being taller than her means absolutely nothing in this world.
There's actually two little action scenes that are reasonably well done, the Labyrinth environment is cool looking, and if you're the kind of person who finds Kirito and Asuna's relationship interesting this episode is endearing. Plus it's at least playing at setting up future conflicts with the unknown observer in the crowd.
