Mr. Carnes Snr. was wounded in the left leg. When Mr. Santini comes over, Mr. Carnes Snr. drops his left crutch, thereby putting weight on his left leg.
Mr. Santini contacts Mr. Hawke using a telephone, yet Mr. Hawke responds using a radio - two completely different systems.
The narcotics runner is asked when the rest of the 100 kilograms will be delivered. The runner responds that he cannot carry 120 pounds upon his back. 100 kilograms is equivalent to about 220 pounds.
