Since late January, Peterson had mostly been keeping a low profile. But law enforcement had been keeping tabs on him. "Wiretaps on phones, tracking vehicles, all of the technology available," Lockyer said.
The attorney general revealed that police had attached a tracking device to Peterson's pickup. "We were careful about that information," Lockyer said.
Keeping that information secret was one reason police and prosecutors worked so hard -- successfully -- to keep all the search warrants sealed.

Sealed warrants or not the Freepers knew immediately when the police confiscated Scotts second pickup and then later brought it back it was because they had put a tracking device on it.
Tehehehehehe! They can maybe put one over on Scotty boy, but not the Freepers.
