Rebecca McCoy tells Price she isn't going to mention the plea deal to her client because she knows he will not take it. However a defense attorney is both ethically and legally obligated to inform their client about any plea bargains proposed by the DA's office, regardless of their opinion on the fairness of the deal. Failure to inform her client of this deal would be grounds to file an appeal based upon ineffective council.
The video footage of the shooter shows him to be quite balding. The waiter interrogated at the 13-minute mark has a nearly full head of hair. Any rookie cop would take one look at him and realize he couldn't possibly be the killer.
In the final scene where McCoy is talking to his daughter as she gets into a taxi, a cameraman is clearly visible filming the taxi from McCoy's left side.
It is stated that the defendant, a New York resident, was able to go to a different state and legally buy a handgun, making the argument that gun control laws need to be stricter. This is incorrect, you cannot legally buy a handgun in a different state and take possession of it, especially if you are a New York resident. The only way a resident of New York could legally buy a handgun in a different state is by having the gun store in that state ship the handgun, assuming that type of handgun is legal in New York, to a FFL licensed gun dealer in New York after it is paid for. The buyer would then need to present their valid New York state pistol permit to the dealer and pass the standard background check, only then would the buyer be allowed to take possession of said handgun. If the defendant went to another state and bought a handgun and was able to get it immediately then he did not buy it legally, which actually shows that gun control laws only go so far.
