As the motorbike shooter pulls up to Lewis and Falsone while driving in the squad car, he fires a couple of shots into the vehicle. He is armed with a .44 Magnum Desert Eagle pistol. The recoil of that caliber pistol would throw the shooter off the dirt bike he is riding yet he stays on the bike.
The forensic tech keeps saying the retrieved bullet is a 50 caliber whole holding it in a clear plastic baggie, but its much too small. It appears to be closer to a 9 millimeter.
