"The scariest part is that you're removing the duty to retreat. That's really there to preserve life."
Unless by retreating instead of acting, you give the advantage to your attacker.
That's the problem with these dolts--they think one size fits all. They don't want people to consider that, just perhaps, the person on scene has a better grasp of what they neeed to do to preserve their safety than the MMM herd of inane cud-chewers. Not a one is qualified to offer tactical defense instruction, but the media presents them as authorities.
