Obviously, there is no solution that will eliminate gun shooting, and there are different opinions on how to reduce potential gun violence.
However, I believe that there are a few components to this discussion, one would be on a macro level and the other on a micro level.
For instance, having stricter gun laws might or might not have an impact on potential gun violence. Yet we can also have a discussion about what if you were to be caught up in an active shooter situation, what would be the best mechanism for you as an individual that would increase your survival probability and also possibly eliminate the active shooter threat from creating further damage?
What if you or someone near you would be carrying a legal weapon and be trained on how to effectively use it, would that reduce the shooters potential for further damage?
