Yes. That lesson was previously known.
that makes perfect sense and probably only occurs when officers have friends in other precincts. Word of mouth.My experience is that lessons learned are shared by those small groups that have national organizations. Bomb Techs share a lot of info because the FBI runs the program for the country. Negotiators seem to share well because a lot of them attend the same training. I think lessons learned at the street level don't get shared nearly so effectively.
