Corrected entry: The cop has been shown the entire movie to have it out for Kale. Always showing up as soon as possible to catch him when he goes outside the boundaries. Then, at the end, the one time that Kale WANTS him to come ASAP, the cop takes his own sweet time. Of course, the cop has no idea that Kale wants him there to save him from a murderer. So it is very out of character for him to suddenly not care about catching Kale violating the house arrest.

Correction: Doing something that is out-of-character is not a plot hole. The cop could have had any number of reasons for not showing up right away. He may simply have gotten tired of responding all the time or felt that Kale was yanking his chain, expecting him to come running every time he stepped over the boundary.
