The prosecutions basic assertion is that SP is a scumbag, and his wife is dead, ergo, he did it. Oh, and he has a boat, and his wife was found in the water.
Did he do it? Heck yes, probably so. But you can't convict somebody based on what amounts to total speculation.
Just ask OJ.
Maybe he and SP can start up a new PI business, to look for the "real killers".
Agree with you. Evidence against Peterson isn't that great.
OJ should have been executed by now though with the evidence against him.
