Poorly Written *Spoilers*
When the main villain (Keaton) is killing Chad in the hallway; the lead actress bumps into a gun and the bag full of diamonds by the terrace entrance. Isn't that where Chad was left for dead? He was on that exact spot and two inches by his face there was a gun! And the bag of diamonds! Why didn't he pick them up before attacking Keaton? How do you not see a bag of diamonds and a silver gun (the two shiniest objects in the room) that are right next to your face?!
