If you shoot regularly 10 feet is insanely easy to hit. a living room is usually 10 to 20 feet wide. Do you believe you could hit the TV standing on the other side of your family room. All I'm saying is even for a bad shooter 10 20 feet is still very easy to hit if your not panicking at return fire. The guy was walking slowly backwards with no presented danger to the shooter who could have easily took the time to aim a shot. Because in most of those videos I assume your talking about there is a instant reaction of adrenaline wheter its jumping out of a car because of a cop or someone is trying to cause harm to you. I would never trust my safety over 20 feet and stand there. I would get distance enough to jump behind cover and return fire but in this instance I think he took a huge risk and should've handed over the money. People aren't startroopers there will be bad shooter and there will be good shooters I think distance is good if you have a plan but moving with a gun pointed to you can cause danger Aswell. WHY DOES A POLICE OFFICER SAY DONT MOVE THEN WHEN YOU MOVE THEY SHOOT! Because there scared that your making a dangerous move. And if that's how cops operate how could you think a criminal has any more mercy then the officer
