OK, I'll bite. All the above portions quoted and that I changed to red ..... are completely wrong, In my opinion.Personally, the minute I see someone pull a gun out even if it's just to brandish it, I take that as a deadly threat. If he turns and walks away then I may just let him go, but it would be hard to not want to stop the guy because no one knows what his next move would be. Is he going to commit another similar crime? Is he going to use that phone to aid him in it? No one knows. If I can stop the guy, then I will. Showing a gun from a normal situation is automatically a crime. If I see a gun and it's not at a gun store or at a range or at a trusted friend or family members house, then I take it as "This person could possibly use this gun to hurt me" and I will do whatever I can to stop the crime being committed and any crime that could be committed afterward.
