A few tips on firearm safety for Riverdale Utah police chief Dave Hansen:
First, modern automatic pistols, such as the Glock .40, come equipped with a switch known as a "safety." The safety, when properly engaged, prevents the pistol from firing accidentally. Best practice dictates that the safety be engaged at all times unless imminent fire is anticipated.
Second, it is also recommended that pistols be left unloaded at all times, again unless imminent need for use is anticipated. This is of course not true for field use, but in one's office at the Riverdale police department there should be little danger of imminent gunplay. When it is necessary to keep the pistol loaded, it is poor practice to "chamber" a round, again unless imminent use is anticipated.
Third, Vincent Vega, as charming as he was, is a poor role model to emulate in handling firearms. Do not wave a pistol around. Never use it as a pointer. This is especially true when the pistol is loaded, a round is chambered, and the safety is not engaged.
Fourth, never attempt to "strip" or dismantle a pistol if you cannot see it, such as when holding it beneath a table or desk. Again, this is especially important when the pistol is loaded, chambered, and the safety is off.
Finally, it would probably be best to pass these tips on to your students the next time you teach a firearms safety class. We're glad no one was seriously hurt.
