re: Michael Peterson vs Scott Peterson - did both of them actually do it?

Detectives in this case, as in most cases, were the absolute drizzling shits. That's what I gather from most true crime documentaries. There was a serial killer in the Seattle area. Police did frick all and couldn't find their own arse with 2 hands and a map. Then when DNA finally popped him decades later, the lead detective had the balls to say to the perp, "Got you motherfricker." Bitch...you got nothing. A computer got him.

In the Scott Peterson case, they zeroed in on him way to early, and moved Heaven and Earth to convict. I honestly believe they found the body (wife and child), and planted it where they knew he was that day...just because they were in too deep and couldn't say "we screwed up trying to hang this guy, while the real killer got away." I'm sure this happens in a lot of cases like this without hard evidence.
