The Plot is Unbelievable

Rating: 6/10 (30 April 2006)

How Chris gets away with murder defies logic and ruins what is a decent movie. After the police find Nola's diary, Chris obviously becomes a prime suspect so in no particular order here is why I think the plot is full of holes:
(1) In the scene where Chris phones Nola and asks her to meet him that evening, her co-worker asks if it is him and she says yes. It would make sense that she would have told her that she is going to meet Chris after work. Don't you think the police would have questioned the co-worker?
(2) With the tenant knocking on the door of Nola's neighbor and knowing when Nola finished at work, the police could easily establish the approximate time of her death. Chloe would be able to tell the police as to what time Chris met her at the theater so his alibi doesn't hold water.
(3) If the police talked with the employee at the theater she could have verified that Chris checked in a tennis bag which was quite heavy, very capable of holding a shotgun. His co-worker at his office (when Chris leaves) notices the bag too so he could verify it, as could Chloe.
(4) Chris takes a cab from Nola's apartment to the theater. He is running late so it is not likely that he walked a distance before hailing a cab. Couldn't the police check with all the cab companies making a pick up close to that location and ask the driver for a description of the person they picked up? They can calculate when Chris would have to have taken a cab as the time frame is quite narrow. If they showed the driver a picture of Chris wouldn't he able to identify him?
(5) The police mention about discreetly checking out the shot guns that Chris' father in law own. Don't you think they would conduct ballistics test on those guns to see if there is a match? Or is it because shot guns cannot be matched using ballistics?
(6) Wouldn't the autopsy on Nola reveal that she is pregnant? Wouldn't that further explain Chris' motive and increase police suspicions?
7) In the end the police conclude that a drug addict killed both Nola and her neighbor but there are no signs of forced entry in to the neighbor's apartment. It doesn't make sense that the neighbor would let in someone she didn't know (she even says that before she lets Chris in). Given that Chris was having an affair with Nola, it would be logical to think that her neighbor had previously met Chris.
(8) Does the drug addict have a "history" or record of using a shot gun or sawed off shotgun? If not, isn't a handgun much easier to conceal so wouldn't the fact that Chris' father in law has a number of shot guns be another clue?
I can even overlook the astronomical odds of a drug addict finding the neighbor's ring, being killed in a shootout, and having the police find the ring in his pocket as part of the theme of there being a lot of luck in life and the ring teetering on the handrail as a tennis ball would on a net but all the above makes the events in this movie totally implausible.
