He thinks he is more than adequately prepared should the need arise to use his weapon.
And he probably is. Most police win most of their gunfights. In large part that is because most BGs aren't any better trained than LE and LE usually has better equipment, IMO. Gunfights don't happen much, and the unusual gunfight or unusual opponent where you need lots of skill is even more unusual. And it is those fights and opponents that get officers hurt. On a more practical note, training takes time and money. How much of the officers time are you willing to pay for with additional taxes. The LE training issue is one that is really hard to work with, and it goes far beyond guns, BTW. Want to hear something really scary? A whole lot of cops out there-- driving at high speed--have only had high school driver's ed as their training in operating a cruiser.
