P1 First Person: Tactical concepts for building entries

Editor's Note: In PoliceOne "First Person" essays, our Members and Columnists candidly share their own unique view of the world. This is a platform from which individual officers can share their own personal insights on issues confronting cops today, as well as opinions, observations, and advice on living life behind the thin blue line. This week’s essay comes from PoliceOne Member member Dan Danaher, an officer with the Livonia (Mich.) PD, and Executive Board Member of Tactical Encounters, Inc.
