I would think he would be questioning what business the police had tracking
Peterson's whereabouts AFTER the crime was commited.

At the time the devices were PROBABLY placed, this was a missing persons
case, and Scott was PROBABLY the prime suspect. The police (and I'm sure
a judge agreed at some point) were trying to surveil a suspect by using
these devices.

but... thats just speculation on my point.

It seems the prosecution is trying him with character assasination after the
fact rather than with evidence of the crime itself. He'll probably wind up
being the first person executed for having an affair.
