Continuity: In the scene where a carload of bad guys drives past the front of Segal's sister's house and riddles the front of the house with machine-gun fire, Segal quickly slams the front door shut, and you can very clearly see all the stunt charges attached to the door.
Other: When Seagal is in the factory in Jamaica, a "Jamaican" bad guy jumps up from behind a barrel, you can see that he is in fact white - you can see the make-up line on his neck, and his wig is crooked.
Continuity: In the closing scene, Seagal is carrying the Jamaican policeman with his head to the right, the view changes to the rear and his head is to the left.
