I am torn between the arguement. I truly do understand not letting the unprepared, uneducated and the overly stress people crammed into a shelter carry knives or even a nerf football for that matter. However, being prepared - mentally, physically and with proper equipment - you wont see me in a shelter (or anywhere else populated). I have been a cop, a firefighter and an EMT. I have seen people at their worse and it usually happens when 2 or more people come together. Classic Darwinism will occur. The strong (or better armed/skilled) will survive. Mix in a few people that is trying to help and a few more that are panicing and just for fun and games - mentally ill and aggressive due to the situation at hand. Ya I can understand not wanting knives or guns in that situation. But like I said - I wouldnt be there in the first or last place.
