The men violated the basic tenets of gun safety. One is to always treat a gun like it?s loaded. Another is to never point your pistol at anything you?re not willing to destroy. Other rules include keeping your finger off the trigger until you?re ready to fire the weapon, and knowing your target ? and what?s beyond the target.
I will assume from the video that the 2 guys are friends and out to have a fun day. Even if its my best friend I don’t trust anyone at the gun range with my safety. Its up to me to stay aware of the situation.
