Well put, Dave.
My best friend is a NYPD LT. with 27 years on the job.
He once joked that police work is the only occupation where those who have never done it feel that they have something to offer to those who do it every day.
I feel the same way about those with only a competition background who feel superior to those with real world armed combat experience.
I suppose it all boils down to just who's opinions we are going to trust our lives to.
