Ok, here's my stance on this issue, you need to fear the criminals with guns, who probably have them illeagily in the first place, the people who took the trouble to get a legit firearm are law abiding, and, for the most part, mentally stable. Of course you will have accidents with people who aren't properly trained, but that works the same way with anything, MA or cars, not just weapons. But remember, i guarantee you that even if we ban firearms, criminals will get them anyway...
