It is interesting you mention this. I watched the video of the first robbery and had I been there with a gun, there would have been nothing I could do other than dish out the cash. There were 2 men, both with guns and if I were there with a gun I may have been able to take out one man but the other would have shot me or someone else before I could do a thing. However, this robbery was different. The robber did not know I was there. I was behind him and had I been carrying I could have easily taken him down. However, I was not and I didn't dare try to rush a man with a gun. I actually had to quietly let the robber know I was there so he wouldn't become startled by seeing another person and then shoot me. As you said, if he has the gun on you first there is not much you can do. However, if you can get your weapon up before he does or catch him off guard you may be able to stop him. Is it safer to just give a robber the money so he will leave while hoping he doesn't shoot you, or to chance it by defending yourself if you can? They say 99% of robberies do not involve shooting or violence. However, if you have the gun turned on you, then being a 99% statistic or a 1% statistic is up to the man pointing the gun at you. I don't like to leave my fate in the hands of others, especially one threatening my life.
