Bart fears his new neighbor might be Sideshow Bob.

!! Tropes:

* AlliterativeName: Walt Warren.
* JurisdictionFriction: [[AvertedTrope Averted]]. While Sideshow Bob was at Five Corners (a place where five states meet) by the time Chief Wiggum found him, police officers from the other states showed up to arrest Bob and his only choice was where he'd be arrested.
* OffOnATechnicality: Bob's plan to kill Bart was shooting from a state; having the bullet cross another one; having Bart being hit in a third state and falling dead in the fourth. No single action could be prosecuted or so Bob believes.
* ShoutOut: Bob said his plan to kill Bart would be the greatest murder ever since [[HarryPotterAndTheHalfBloodPrince Snape killed Dumbledore]].
