The primary reason good experienced cops are retiring is because of the constant second-guessing.
What you're left with is a bunch of gutless paper-pushers who wear their uniforms, their badges, and their little guns, but don't know jack about how to take down a perp in a hostage situation. We learned how to take down a target so fast he doesn't have time to shit himself before he's dead-meat. You have to know how to enter a building and fan out inside a room and minimize your exposure. Somebody's gonna get shot or at least shot at while the other guys are shooting the SOB in the face.
The fact is....when you know what you're doing you have the confidence needed to do the job.
But that isn't what happened here.
