Completely agree with all the statements here. Why the hell are you approaching a supposed armed person with a taser. You already know it's not going to work worth a damn on that big puffy jacket anyway. Should have been a long gun deployment from the start.
To me the officer is a perfect example of mindset failure. Why are you begging the radio to help you? No one is going to help you, so help your damn self. Get in that car and drive your ass towards the hospital code 3. Get up and fight for your life.
