Plot hole: At the end, when Chris finds the informant's phone, he sees that there are 2 voicemail messages. Instead of listening to them, he calls the last number, which reveals Abel is responsible for the break-in when he answers and in turn reveals to Abel that Chris knows about the break-in. It would make more sense to just listen to the voicemails, as Chris became immediately suspicious when he saw them. Considering Chris called the last number, he must have known that the last number was also the person who left the voicemails. Very deliberately done to bring realizations between Chris and Abel for a climax.
Continuity mistake: In the scene in which Abel is facing the gunmen with the shotgun, after Abel takes the gun away from the gunman and holds it up under his chin, the view changes from Abel's face to the gunman's face. When Abel's face is shown, the gunman's face is low, but when it switches to the gunman's face, you can note that his head is tilted up higher, and vice versa.
Continuity mistake: Lisa is in the pool and kisses Chris who just had a chat with the creepy Abel Turner. She has her hands on the edge of the pool when the kiss begins, but at the cut her hands are underwater and Chris' fingers reach around the edge. (00:18:40)
Continuity mistake: Abel Turner at the beginning of the movie is having a discipline-filled breakfast with his kids. Marcus arrives at the table and his glass of orange juice is full practically to the brim. In any other angle, the level of liquid is lower. (00:03:00)
Other mistake: The way Chris finds the phone is impossible: the phone magically slips from under the bed, so it's within Chris's eyesight.
Answer: Abel was mentally unstable and that drove his overall behavior. His initial antagonism about Chris and Lisa started with a variety of factors including them being an inter-racial couple, Chris' smoking, and the couple listening to hip hop music. This was all exaggerated in Abel's mind, and continued festering. Abel's late wife had an affair with a white man, which seems to be a factor in his objection to any inter-racial relationship and distrust of white men. It's implied that Abel's extreme, controlling behavior is what led to his wife's infidelity.
