If you are in charge of your department's firearms training program take a look at your approved course manual. When was the last time it was updated? Are you even teaching what is in the book? It could be that your program has evolved but your material doesn't reflect it. Are you teaching tactics that are proven and practical or are you simply teaching what's been in the book for the last thirty years?
Too many lawmen look at a Range assignment as a place to chill out or skate for awhile. They follow the old playbook, push their students through, and collect a paycheck. Is the material you are providing them up to date and practical or are you simply going through the motions and doing what's always been done? The choice is up to you.
