GPS evidence proved that Scott Peterson, who was falsely accused of
murdering Laci, was concerned about the course of the investigation.
As a matter of fact, he evidently went to the Bay, more out of
disbelief about the course of the investigation, than out of fear that
the police would discover his wife's body. When Scott Peterson went to
the Bay, he only stayed 2 or 3 minutes each time, and that is clearly
not a man who was concerned about what the police were doing. The
police had already shocked and isolated Scott Peterson by treating him
like a guilty suspect, and Scott didn't need any more than 2 or 3
minutes to confirm the fact the police were not investigating the
disappearance of Laci, they were merely seeking to confirm their
suspicions at best and pursuing the leads that the real murderers were
advancing, at worst.

Perhaps the police are angry at Scott Peterson because he was aware of
the fact that they were tailing him to the marina and having made fun
of them, they think that GPS tracking devices prove that the police
essentially duped a confession. They did not.

Since when is Scott denied the opportunity to observe the
investigation into his own wife's murder? -- if anybody cares to call
tailing Scott Peterson, an "investigation". In the final analysis, the
police were tracking Scott Peterson when they should have been looking
for Laci, and they are pursueing Scott at all cost, to evade the
simple truth.
