That's the defense's argument, sure. I am very much aware of that.If it was provably the Klingon's knife, then the chances of M'Benga having got hold of it for purposes of premeditated murder are much reduced - as are the chances of him having attacked an armed Klingon.
I'd like to know what the sensor data said. We saw what the witness saw (nothing useful). I'd like to know how the investigation proceeds. I'd like to see the prosecution's argument, because I think it would be very compelling.There was an investigation. The one witness to the event provided testimony, and the security chief said the limited sensor data appeared to corroborate it. What other evidence is there to examine?
I'm not in the show. I'm a viewer. I want that information, because without it the whole thing looks weak, like he got away with murder.
