Factual error: Stanley's parents say they can't afford a lawyer, and go to court without one. A lawyer should've been provided for them free of charge, as it's one of your rights, which he would've been read when he was arrested.
Factual error: When Stanley runs after Zero who is lost and finds him passed out, Zero offers Stanley "sploosh" which we deduce is rotten peaches from Sam's boat which they are taking shelter in. Had the peaches survived both the descent to the bottom of the lake after Sam was killed AND the effects of time, they would be extremely fermented and would be alcoholic. Stanley and especially Zero, would be drunk and would surely dehydrate to death or at least not be able to climb "God's Thumb" coherently.
