Klosky and Lerman don't specifically articulate it in their column, but one might surmise that they believe such a program would be a compelling career opportunity for a young person who otherwise might choose another profession. This value proposition, would be better than say, becoming an entry-level software engineers with a salary multiples better than a first-year police apprentice not yet even sworn to fully enforce the law.
Sorry—that's probably not going to happen.
All is Not Lost
The suggestion offered by Klosky and Lerman looks great on paper. Long-term recruiting / training programs created and maintained with the stated intention of attracting interested young people into the police profession sounds like—and, in fact, is—an outstanding idea. The problem is, simply standing up a six-week program for high school kids seems to be too much for many agencies to manage. Launching something as ambitious as what is proposed in this Newsweek piece borders on fantasy.
Consider the fact that there are thousands upon thousands of vacant apprenticeships in vocations commonly called "the trades"—construction, HVAC engineering, pipe-fitting, plumbing, vehicle mechanics, welding, and the like—despite their high-paying wages and virtual guarantee that you won't get shot at on the job.
