Now, I realize that you say that guns should not be used in widespread crowds because when used most likely they will hit and injure other individuals. But what will we use to counter this. In some cases people rules. The only way to counter guns would be with GUNS. Guns could be used to deter potential threats to the crowds by symbolically saying that, "There is security, they are armed and serious." Guns aren't just handled by criminals they are also handled by the people trying to protect you.
As said before, if an individual happens to have a gun and he intends to hurt innocent civilians I can almost guarantee there would be ample security around the area to prevent or terminate any threats. Thank you for this debate.
