While the exact charges against Madea are not specified at the start of the movie, when she is in court all charges are dismissed due to the police not reading her "Miranda". The sole time Miranda is applicable under U.S. case law is when there is custodial interrogation by the police (questioning where the suspect is not free to leave). Any crimes the police witness they do not need to interrogate the suspect. The violation of fleeing the police is shown and battery on an officer is inferred. Miranda would not need to be read for either of these offenses to be proved, and a lack of it being read would have no bearing on the validity of the charges. If the police violate a suspect's rights by custodial interrogation without the Miranda warning, the sole penalty for the violation is the suppression of any statements made by the suspect.
In the beginning of the movie, when Mable's criminal record is shown, her year of birth is shown to be 1962, which would make her 47 years old in 2009, but the character Madea/Mable is portrayed to be much older than 47.
In the scene when Chuck is typing, studying a case for his friend Joshua, the laptop should be on. He is using a MacBook Pro. When MacBook Pros are on, the Apple logo on the back of the notebook would be illuminated white. Thus since the logo isn't lit, the computer is off.
