When Danny is looking through the pictures on Eddie's camera it initially indicates that there are 53 pictures on the memory card (top right corner of the camera screen), however when he finds the pictures taken at the docks and shows them to Steve the counter indicates that there are only 4 pictures on the memory card.
After the fight at the end, Maggie is badly injured - a dislocated shoulder at least - and lying on the ground when a police officer just picks her up in his arms and carries her away. The very last thing you should do to anyone who is injured is move them, let alone pick them up this way. Paramedics should carefully place her on a board or stretcher to move, after identifying her injuries. The only reason to move a badly injured person is to ensure they can breathe if unconscious.
