While talking in the car about A.J. having heard the murder over the phone, both Maya and James claim that is inadmissible as hearsay but hearsay doesn't mean something a person heard directly but rather from a third party such as if Pope had told him about the murder. Anything a person hears for themselves is admissible.
When Ben is chasing A.J his gun is on his right side of his waist, but the scene after James looks down the alley to see were they are Ben's gun is on the left and just before A.J jumps on the trampoline when Ben appears his gun is back on the right...
At the bachelor party at the club scene Ben is counting the number of shots the assassin fired. He counts to 15 and says the assassin needs to reload; the FN Five-seveN is known for its 20 round standard capacity and alternate 10 round magazine (for markets with capacity restrictions) there is no 15 round version.
When Port Commissioner Griffin receives the call from Antonio Pope at the beginning of the film; the time on his wall clock in his office is 9:20. A short time later when he drops his phone, the time on the phone is reading as 1:44pm.
Also, when we see Griffin's phone lying on the floor, the call duration is frozen at 0.36 - as Griffin never disconnected the call from Pope, the call duration should be continuing to count up.
Note - even if Griffin had stopped/disconnected the call (which he didn't), the actual call duration should be around 0:51 seconds.
This could be irrelevant anyway as Pope was showing as a 'Blocked Caller' (as shown on Griffin's phone), Therefore it is likely that the call would never have gone through in the first place.... more than likely, the call should have shown as 'Unknown Caller/ID' - and not as 'Blocked'.
When Ben (Kevin Hart) is on the beach and following A.J's instruction, you can see him taking a can from the pyramid of cans on the booth counter, and in the next shot the can is spotted on the top of the pyramid again.
