CHAPEL HILL, N.C. Shawn Turschak of Chapel Hill was tired of someone stealing McCain-Palin campaign signs from his yard. Turschak, with a degree in electrical engineering, hooked up a third sign to a power source for an electric pet fence Monday and also put up a surveillance camera.

The News & Observer of Raleigh reported that a 9-year-old boy with an Obama-Biden sign grabbed the McCain-Palin sign and got a jolt on Tuesday.

The boy's father, Andrew Noble, upset that his son had been shocked, showed up at Turschak's door. Soon an Orange County sheriff's deputy also showed up at the Turschak's home.

Noble said his son just wanted to see how the sign was put together. Turschak said the boy intended to swap out the signs.

Sheriff Lindy Pendergrass said he doesn't plan to file charges.
