I just finished reading the manga this morning and this thought popped into my head, so here it is:
Speak No Evil: Misa Amane--> during the entire story Misa was one of the only people to not only know about Kira's identity but also vehemently support him, Misa had many chances to reveal Kira's identity but didn't, and was shown to never dwell too much on the moral aspects of light's actions.
Hear No Evil: Shuichi Aizawa--> This could be said about the entirety of the kira task force, but I decided to use Aizawa as an example for this. From the start the kira task force were presented with a lot of evidence that could support L's claims, but instead they never dwelled on it too much and never paid it any attention, you could also say the during light's secret meetings with takada when Aizawa could only listen to their conversations, he could not hear anything that could be used to implicate light.
See No Evil: Soichiro Yagami--> Just like the rest of the kira task force, Soichiro was too blinded by his relation with light to ever clearly see anything he does as evidence to back L's accusation, you could also say that him seeing light's name with the shinigami eyes before his death to prove his innocence is seeing no evil within light in and of itself.
Anyway, I had more to say but I forgor💀
