With one exception - Peterson talked himself into prison without parole.
Laundrie had amazing self-discipline and never locked himself into a defense narrative he could not verify or explain.
Of course he hasn’t. The only people he’s talked to are his parents. They probably think they have parental confidentiality. Either that or they know they will go down as accessories after the fact. Laundri isn’t talking himself into a corner because he isn’t talking.
