Good advice, and not just for cops. The only thing I would add is: Get the weapon out if you think you may need it!
This is a knife wound story, this is what a knife will do, this is why cops don’t shoot to wound or shoot weapons free. The equation is very simple, shoot center mass and shoot to stop the threat…..the threat that will allow me and my partners to go home at night, the threat that will allow others to remain blissfully unaware of what goes on in the dark corners of the night, and the threat that allows others to criticize and second guess everything we do based on a TV script and special effects.
Stay safe, and make sure you go home every day!
