Babylon 5 (1994)

S2E14 There All the Honor Lies

Sheridan finds himself in a life-threatening situation when he is attacked by Lovell, a Minbari. In an act of self-defense, he is compelled to take Lovell's life. However, a Minbari who observes the confrontation accuses Sheridan of being the aggressor, asserting that Lovell was the victim. This accusation carries weight, as it is well-known that Minbari are considered incapable of falsehoods.
