At least from my perspective, the trial is meant to be contrived and a farce. From Meursault's perspective (which I agree that he can be an unreliable narrator) everything happening around him is inconsequential; he reflects that death-even of someone so "close" to him as his mother-doesn't matter as the end would always come. Meursault is on trial for his disposition, rather than the actual murder. The prosecution argues that Meursault is guilty due to his aloofness rather than any discussion of the murder (the defense openly questions whether Meursault is on trial for the murder of the arab or the murder of his mother!). At least for me, this difference was what _The Stranger_ was about; this inherent clash between indifference and the human rejection of the "gentle indifference of the universe". The fact that Meursault's unreliable narrator aspect comes about of the confrontation between the priest(?) and himself makes me think that Meursault too was hiding under this coating of lucidity, where he (and others who pretend to be stoics in the face of the absurd) will eventually break down. I reccomend reading _The Myth of Sisyphus_, especially the third and fourth parts, for Camus' explanation of the absurd hero.
Also, could you link the critiques? They sound interesting and I'd like to read them.
